This paper presents the integration and channel characterization of a highly integrated dual-band digital beamforming space-borne synthetic aperture radar (SAR) receiver. The proposed SAR sensor is a low-cost, lightweight, low-power consumption, and dual-band (X/Ka) dual-polarized module ready for the next-generation space-borne SAR missions. In previous works, by the authors, the design and experimental characterization of each sub-system was already presented and discussed. This work expands upon the previous characterization by providing an exhaustive experimental assessment of the fully integrated system. As it will be shown, the proposed tests were used to validate all the instrument channels in a set-up where the SAR sensor was illuminated by an external source minim the ground reflected waves. Test results demonstrate how the system channels are properly operating allowing the reception of the input signals and their processing in the digital domain. The possibility to easily implement a calibration procedure has also been validated to equalize, in the digital domain, the unavoidable amplitude differences between the different channels.

DOI: 10.1016/j.microrel.2020.113799, (RESCUE)
This work introduces an embedded approach for the prediction of Solar Particle Events (SPEs) in space applications by combining the real-time Soft Error Rate (SER) measurement with SRAM-based detector and the offline trained machine learning model. The proposed approach is intended for the self-adaptive fault-tolerant multiprocessing systems employed in space applications. With respect to the state-of-the-art, our solution allows for predicting the SER 1 h in advance and fine-grained hourly tracking of SER variations during SPEs as well as under normal conditions. Therefore, the target system can activate the appropriate mechanisms for radiation hardening before the onset of high radiation levels. Based on the comparison of five different machine learning algorithms trained with the public space flux database, the preliminary results indicate that the best prediction accuracy is achieved with the recurrent neural network (RNN) with long short-term memory (LSTM).

DOI: 10.1142/S0218126620502187
In this paper, two approaches are evaluated using the Full Error Detection and Correction(FEDC) method for a pipelined structure. The approaches are referred to as Full Duplication with Comparison (FDC) and Concurrent Checking with Parity Prediction (CCPP). Aforementioned approaches are focused on the borderline cases of FEDC method which implement Error Detection Circuit (EDC) in two manners for the purpose of protection of combinational logic to address the soft errors of unspeci¯ed duration. The FDC approach implements a full duplication of the combinational circuit, as the most complex and expensive implementation of the FEDC method, and the CCPP approach implements only the parity prediction bit, being the simplest and cheapest technique, for soft error detection. Both approaches are capable of detecting soft errors in the combinational logic, with single faults being injected into the design. On the one hand, the FDC approach managed to detect and correct all injected faults while the CCPP approach could not detect multiple faults created at the output of combinational circuit. On the other hand, the FDC approach leads to higher power consumption and area increase compared to the CCPP approach.

This work presents fully-integrated modular wideband frequency interleaving (FI) transmitter and receiver for high data rate communication applications. At the transmitter side three independent I/Q baseband channels are up-converted to different intermediate frequencies (IF) and then interleaved. At the receiver side the interleaved signals are down-converted and separated back to each independent channel. Single-ended inputs and outputs are utilized in order to reduce the pin count, for a more practical realization and higher potential toward future system scaling. Special design techniques are followed to minimize cross-talk and inter-modulation products between the channels. All circuits are manufactured and measured in a 130nm SiGe:C BiCMOS technology with fT / fmax = 300 / 500 GHz. The FI transmitter achieves a channel bandwidth of 2.5 GHz with less than 3 dB difference across the different channels till 15 GHz IF. It consumes 560mW from 2.5V and 3.3V supplies, and occupies a silicon area of 1.9mm2. The FI receiver achieves a baseband channel bandwidth of 2.5GHz with a 1 dB difference between the channels till the same IF. It consumes 890mW from 2.5V and 3.3V supplies, and has a chip area of 1.55mm2. The circuits are deployed in a communication experiment, firstly in a back-to-back test with direct cable connection, demonstrating a data rate of 15.6 Gb/s across the three IQ channels with a 16- QAM modulation scheme and worst case transmitter-to-receiver (Tx-to-Rx) error vector magnitude (EVM) of -18.6 dB. Then a wireless experiment is performed with a 240 GHz front-end with on-chip antenna, demonstrating a data rate of 7.8 Gb/s with QPSK modulation and worst case EVM of -8.3 dB across a wireless link of 15 cm. To the best of the authors’ knowledge this is the first work that demonstrates a wireless transmission at sub-THz carrier frequencies utilizing frequency interleaving architectures.

Thermal Magnetic Resonance (ThermalMR) leverages radio frequency (RF) induced heating to examine the role of temperature in biological systems and disease. To advance RF heating with multi-channel RF antenna arrays and overcome the shortcomings of current RF signal sources, this work reports on a 32-channel modular signal generator (SGPLL). The SGPLL was designed around phase-locked loop (PLL) chips and a field-programmable gate array chip. To examine the system properties, switching/settling times, accuracy of RF power level and phase shifting were characterized. Electric field manipulation was successfully demonstrated in deionized water. RF heating was conducted in a phantom setup using self-grounded bow-tie RF antennae driven by the SGPLL. Commercial signal generators limited to a lower number of RF channels were used for comparison. RF heating was evaluated with numerical temperature simulations and experimentally validated with MR thermometry. Numerical temperature simulations and heating experiments controlled by the SGPLL revealed the same RF interference patterns. Upon RF heating similar temperature changes across the phantom were observed for the SGPLL and for the commercial devices. To conclude, this work presents the first 32-channel modular signal source for RF heating. The large number of coherent RF channels, wide frequency range and accurate phase shift provided by the SGPLL form a technological basis for ThermalMR controlled hyperthermia anti-cancer treatment.

(27) Soft Error Detection and Correction Architecture for Asynchronous Bundled Data Designs

IEEE Transactions on Circuits and Systems I 67(12), 4883 (2020)
DOI: 10.1109/TCSI.2020.2998911, (ENROL)
In this paper, an asynchronous design for soft error detection and correction in combinational and sequential circuits is presented. The proposed architecture is called Asynchronous Full Error Detection and Correction (AFEDC). A custom design flow with integrated commercial EDA tools generates the AFEDC using the asynchronous bundled-data design style. The AFEDC relies on an Error Detection Circuit (EDC) for protecting the combinational logic and fault-tolerant latches for protecting the sequential logic. The EDC can be implemented using different detection methods. For this work, two boundary variants are considered, the Full Duplication with Comparison (FDC) and the Partial Duplication with Parity Prediction (PDPP). The AFEDC architecture can handle single events and timing faults of arbitrarily long duration as well as the synchronous FEDC, but additionally can address known metastability issues of the FEDC and other similar synchronous architectures and provide a more practical solution for handling the error recovery process. Two case studies are developed, a carry look-ahead adder and a pipelined non-restoring array divider. Results show that the AFEDC provides equivalent fault coverage when compared to the FEDC while reducing area, ranging from 9.6% to 17.6%, and increasing energy efficiency, which can be up to 6.5%.

DOI: 10.1007/s10470-020-01651-8
As VLSI design moves into ultra-deep-submicron technologies, timing margins added to the clock period are mandatory, to ensure correct circuit behavior under worst-case conditions. Timing resilient architectures emerged as a promising solution to alleviate these worst-case timing margins. Blade is an asynchronous timing resilient template that leverages the advantages of both asynchronous and timing resilient techniques. However, Blade still presents challenges regarding its testability, which hinders its commercial or large-scale application. This paper demonstrates that scan chains can be prohibitive for Blade due to their high silicon costs, which can reach more than 100%. Then, it proposes an alternative test approach that allows concurrent testing, stuck-at, and delay testing. The test approach is based on the reuse of the Blade features to provide testability, with silicon area overheads between 4% and 7%. Also, the proposed test methodology demonstrated that Blade could be tested in different phases, such as manufacturing, for stuck-at and delay faults, with adequate fault coverage between 70% and 100%.

DOI: 10.1016/j.mejo.2019.104683, (SEPHY)
A triple modular redundancy (TMR) based design technique for double cell upsets (DCUs) mitigation is investigated in this paper. This technique adds three extra self-voter circuits into a traditional TMR structure to enable the enhanced error correction capability. Fault-injection simulations show that the soft error rate (SER) of the proposed technique is lower than 3% of that of TMR. The implementation of this proposed technique is compatible with the automatic digital design flow, and its applicability and performance are evaluated on an FIFO circuit.

Millimeter wave (mmWave) communication has emerged as a key technology for achieving high data-rates and low latency in 5G networks. Radio-frequency (RF) or analog beamforming is used to provide additional (beamforming) gain to compensate for propagation phenomena in the mmWave spectrum. In this letter, we analyzed the effects of residual transceiver impairments on the performance of a single-user mmWave RF beamforming system. We derived the closed-form expressions of the ergodic capacity in both Line-of-Sight (LoS) and Non-Line-of-Sight (NLoS) channels. The derived formulas are applicable for both perfect and codebook-based beam alignment. In the former, they are exact, while in the latter are approximate, but with a high degree of accuracy. The theoretical findings are verified by Monte-Carlo simulations showing an excellent agreement.

This paper presents an overview of semiconductor materials used in gas sensors, their technology, design and application. Semiconductor materials include metal oxides, conducting polymers, carbon nanotubes and 2D materials. Metal oxides are most often the first choice due to their ease of fabrication, low cost, high sensitivity, and stability. Some of their disadvantages are low selectivity and high operating temperature. Conducting polymers have the advantage of a low operating temperature and can detect many organic vapors. They are flexible but affected by humidity. Carbon nanotubes are chemically and mechanically stable and are sensitive towards NO and NH3, but need dopants or modifications to sense other gases. Graphene, transition metal chalcogenides, boron nitride, transition metal carbides/nitrides, metal organic frameworks and metal oxide nanosheets as 2D materials represent gas-sensing materials of the future, especially in medical devices, such as breath sensing. This overview covers the most used semiconducting materials in gas sensing, their synthesis methods and morphology, especially oxide nanostructures, heterostructures, and 2D materials, as well as sensor technology and design, application in advance electronic circuits and systems, and research challenges from the perspective of emerging technologies.

We investigate photocurrents driven by femtosecond laser excitation of a (sub)-nanometer tunnel junction in an ultrahigh vacuum low-temperature scanning tunneling microscope (STM). The optically driven charge transfer is revealed by tip retraction curves showing a current contribution for exceptionally large tip-sample distances, evidencing a strongly reduced effective barrier height for photoexcited electrons at higher energies. Our measurements demonstrate that the magnitude of the photo-induced electron transport can be controlled by the laser power as well as the applied bias voltage. In contrast, the decay constant of the photocurrent is only weakly affected by these parameters. Stable STM operation with photoelectrons is demonstrated by acquiring constant current topographies. An effective non-equilibrium electron distribution as a consequence of multiphoton absorption is deduced by the analysis of the photocurrent using a one-dimensional potential barrier model.

DOI: 10.1016/j.sse.2019.107746
The physically meaningful Boltzmann-Arrhenius-Zhurkov (BAZ) model has been applied to predict the integrated circuit reliability. The model has been modified taking into account the impact of physical defects and process variations (and, consequently, integrated circuit yield) on the stress-free failure activation energy. The probability of non-failure (reliability) and corresponding mean-time-to-failure (MTTF) can be estimated from the failure-oriented-accelerated-testing (FOAT) geared by the modified BAZ model. The concept has been elaborated and illustrated on an application example.

This paper presents the integration and channel characterization of a highly integrated dual-band digital beamforming space-borne synthetic aperture radar (SAR) receiver. The proposed SAR sensor is a low-cost, lightweight, low-power consumption, and dual-band (X/Ka) dual-polarized module ready for the next-generation space-borne SAR missions. In previous works, by the authors, the design and experimental characterization of each sub-system was already presented and discussed. This work expands upon the previous characterization by providing an exhaustive experimental assessment of the fully integrated system. As it will be shown, the proposed tests were used to validate all the instrument channels in a set-up where the SAR sensor was illuminated by an external source minim the ground reflected waves. Test results demonstrate how the system channels are properly operating allowing the reception of the input signals and their processing in the digital domain. The possibility to easily implement a calibration procedure has also been validated to equalize, in the digital domain, the unavoidable amplitude differences between the different channels.

DOI: 10.1016/j.microrel.2020.113799, (RESCUE)
This work introduces an embedded approach for the prediction of Solar Particle Events (SPEs) in space applications by combining the real-time Soft Error Rate (SER) measurement with SRAM-based detector and the offline trained machine learning model. The proposed approach is intended for the self-adaptive fault-tolerant multiprocessing systems employed in space applications. With respect to the state-of-the-art, our solution allows for predicting the SER 1 h in advance and fine-grained hourly tracking of SER variations during SPEs as well as under normal conditions. Therefore, the target system can activate the appropriate mechanisms for radiation hardening before the onset of high radiation levels. Based on the comparison of five different machine learning algorithms trained with the public space flux database, the preliminary results indicate that the best prediction accuracy is achieved with the recurrent neural network (RNN) with long short-term memory (LSTM).

DOI: 10.1142/S0218126620502187
In this paper, two approaches are evaluated using the Full Error Detection and Correction(FEDC) method for a pipelined structure. The approaches are referred to as Full Duplication with Comparison (FDC) and Concurrent Checking with Parity Prediction (CCPP). Aforementioned approaches are focused on the borderline cases of FEDC method which implement Error Detection Circuit (EDC) in two manners for the purpose of protection of combinational logic to address the soft errors of unspeci¯ed duration. The FDC approach implements a full duplication of the combinational circuit, as the most complex and expensive implementation of the FEDC method, and the CCPP approach implements only the parity prediction bit, being the simplest and cheapest technique, for soft error detection. Both approaches are capable of detecting soft errors in the combinational logic, with single faults being injected into the design. On the one hand, the FDC approach managed to detect and correct all injected faults while the CCPP approach could not detect multiple faults created at the output of combinational circuit. On the other hand, the FDC approach leads to higher power consumption and area increase compared to the CCPP approach.

This work presents fully-integrated modular wideband frequency interleaving (FI) transmitter and receiver for high data rate communication applications. At the transmitter side three independent I/Q baseband channels are up-converted to different intermediate frequencies (IF) and then interleaved. At the receiver side the interleaved signals are down-converted and separated back to each independent channel. Single-ended inputs and outputs are utilized in order to reduce the pin count, for a more practical realization and higher potential toward future system scaling. Special design techniques are followed to minimize cross-talk and inter-modulation products between the channels. All circuits are manufactured and measured in a 130nm SiGe:C BiCMOS technology with fT / fmax = 300 / 500 GHz. The FI transmitter achieves a channel bandwidth of 2.5 GHz with less than 3 dB difference across the different channels till 15 GHz IF. It consumes 560mW from 2.5V and 3.3V supplies, and occupies a silicon area of 1.9mm2. The FI receiver achieves a baseband channel bandwidth of 2.5GHz with a 1 dB difference between the channels till the same IF. It consumes 890mW from 2.5V and 3.3V supplies, and has a chip area of 1.55mm2. The circuits are deployed in a communication experiment, firstly in a back-to-back test with direct cable connection, demonstrating a data rate of 15.6 Gb/s across the three IQ channels with a 16- QAM modulation scheme and worst case transmitter-to-receiver (Tx-to-Rx) error vector magnitude (EVM) of -18.6 dB. Then a wireless experiment is performed with a 240 GHz front-end with on-chip antenna, demonstrating a data rate of 7.8 Gb/s with QPSK modulation and worst case EVM of -8.3 dB across a wireless link of 15 cm. To the best of the authors’ knowledge this is the first work that demonstrates a wireless transmission at sub-THz carrier frequencies utilizing frequency interleaving architectures.

Thermal Magnetic Resonance (ThermalMR) leverages radio frequency (RF) induced heating to examine the role of temperature in biological systems and disease. To advance RF heating with multi-channel RF antenna arrays and overcome the shortcomings of current RF signal sources, this work reports on a 32-channel modular signal generator (SGPLL). The SGPLL was designed around phase-locked loop (PLL) chips and a field-programmable gate array chip. To examine the system properties, switching/settling times, accuracy of RF power level and phase shifting were characterized. Electric field manipulation was successfully demonstrated in deionized water. RF heating was conducted in a phantom setup using self-grounded bow-tie RF antennae driven by the SGPLL. Commercial signal generators limited to a lower number of RF channels were used for comparison. RF heating was evaluated with numerical temperature simulations and experimentally validated with MR thermometry. Numerical temperature simulations and heating experiments controlled by the SGPLL revealed the same RF interference patterns. Upon RF heating similar temperature changes across the phantom were observed for the SGPLL and for the commercial devices. To conclude, this work presents the first 32-channel modular signal source for RF heating. The large number of coherent RF channels, wide frequency range and accurate phase shift provided by the SGPLL form a technological basis for ThermalMR controlled hyperthermia anti-cancer treatment.

IEEE Transactions on Circuits and Systems I 67(12), 4883 (2020)
DOI: 10.1109/TCSI.2020.2998911, (ENROL)
In this paper, an asynchronous design for soft error detection and correction in combinational and sequential circuits is presented. The proposed architecture is called Asynchronous Full Error Detection and Correction (AFEDC). A custom design flow with integrated commercial EDA tools generates the AFEDC using the asynchronous bundled-data design style. The AFEDC relies on an Error Detection Circuit (EDC) for protecting the combinational logic and fault-tolerant latches for protecting the sequential logic. The EDC can be implemented using different detection methods. For this work, two boundary variants are considered, the Full Duplication with Comparison (FDC) and the Partial Duplication with Parity Prediction (PDPP). The AFEDC architecture can handle single events and timing faults of arbitrarily long duration as well as the synchronous FEDC, but additionally can address known metastability issues of the FEDC and other similar synchronous architectures and provide a more practical solution for handling the error recovery process. Two case studies are developed, a carry look-ahead adder and a pipelined non-restoring array divider. Results show that the AFEDC provides equivalent fault coverage when compared to the FEDC while reducing area, ranging from 9.6% to 17.6%, and increasing energy efficiency, which can be up to 6.5%.

As VLSI design moves into ultra-deep-submicron technologies, timing margins added to the clock period are mandatory, to ensure correct circuit behavior under worst-case conditions. Timing resilient architectures emerged as a promising solution to alleviate these worst-case timing margins. Blade is an asynchronous timing resilient template that leverages the advantages of both asynchronous and timing resilient techniques. However, Blade still presents challenges regarding its testability, which hinders its commercial or large-scale application. This paper demonstrates that scan chains can be prohibitive for Blade due to their high silicon costs, which can reach more than 100%. Then, it proposes an alternative test approach that allows concurrent testing, stuck-at, and delay testing. The test approach is based on the reuse of the Blade features to provide testability, with silicon area overheads between 4% and 7%. Also, the proposed test methodology demonstrated that Blade could be tested in different phases, such as manufacturing, for stuck-at and delay faults, with adequate fault coverage between 70% and 100%.

A triple modular redundancy (TMR) based design technique for double cell upsets (DCUs) mitigation is investigated in this paper. This technique adds three extra self-voter circuits into a traditional TMR structure to enable the enhanced error correction capability. Fault-injection simulations show that the soft error rate (SER) of the proposed technique is lower than 3% of that of TMR. The implementation of this proposed technique is compatible with the automatic digital design flow, and its applicability and performance are evaluated on an FIFO circuit.

(38) On the Impact of Residual Transceiver Impairments in mmWave RF Beamforming Systems

Millimeter wave (mmWave) communication has emerged as a key technology for achieving high data-rates and low latency in 5G networks. Radio-frequency (RF) or analog beamforming is used to provide additional (beamforming) gain to compensate for propagation phenomena in the mmWave spectrum. In this letter, we analyzed the effects of residual transceiver impairments on the performance of a single-user mmWave RF beamforming system. We derived the closed-form expressions of the ergodic capacity in both Line-of-Sight (LoS) and Non-Line-of-Sight (NLoS) channels. The derived formulas are applicable for both perfect and codebook-based beam alignment. In the former, they are exact, while in the latter are approximate, but with a high degree of accuracy. The theoretical findings are verified by Monte-Carlo simulations showing an excellent agreement.

This paper presents an overview of semiconductor materials used in gas sensors, their technology, design and application. Semiconductor materials include metal oxides, conducting polymers, carbon nanotubes and 2D materials. Metal oxides are most often the first choice due to their ease of fabrication, low cost, high sensitivity, and stability. Some of their disadvantages are low selectivity and high operating temperature. Conducting polymers have the advantage of a low operating temperature and can detect many organic vapors. They are flexible but affected by humidity. Carbon nanotubes are chemically and mechanically stable and are sensitive towards NO and NH3, but need dopants or modifications to sense other gases. Graphene, transition metal chalcogenides, boron nitride, transition metal carbides/nitrides, metal organic frameworks and metal oxide nanosheets as 2D materials represent gas-sensing materials of the future, especially in medical devices, such as breath sensing. This overview covers the most used semiconducting materials in gas sensing, their synthesis methods and morphology, especially oxide nanostructures, heterostructures, and 2D materials, as well as sensor technology and design, application in advance electronic circuits and systems, and research challenges from the perspective of emerging technologies.

We investigate photocurrents driven by femtosecond laser excitation of a (sub)-nanometer tunnel junction in an ultrahigh vacuum low-temperature scanning tunneling microscope (STM). The optically driven charge transfer is revealed by tip retraction curves showing a current contribution for exceptionally large tip-sample distances, evidencing a strongly reduced effective barrier height for photoexcited electrons at higher energies. Our measurements demonstrate that the magnitude of the photo-induced electron transport can be controlled by the laser power as well as the applied bias voltage. In contrast, the decay constant of the photocurrent is only weakly affected by these parameters. Stable STM operation with photoelectrons is demonstrated by acquiring constant current topographies. An effective non-equilibrium electron distribution as a consequence of multiphoton absorption is deduced by the analysis of the photocurrent using a one-dimensional potential barrier model.

DOI: 10.1016/j.sse.2019.107746
The physically meaningful Boltzmann-Arrhenius-Zhurkov (BAZ) model has been applied to predict the integrated circuit reliability. The model has been modified taking into account the impact of physical defects and process variations (and, consequently, integrated circuit yield) on the stress-free failure activation energy. The probability of non-failure (reliability) and corresponding mean-time-to-failure (MTTF) can be estimated from the failure-oriented-accelerated-testing (FOAT) geared by the modified BAZ model. The concept has been elaborated and illustrated on an application example.
