In this paper, a SET pulse width model derived from SPICE simulations is presented. The model expresses the SET pulse width in terms of particle’s LET, target inverter’s drive strength and supply voltage. A bias-dependent current source was employed to model the SET current pulse, thus providing better accuracy compared to similar approaches based on the widely used double-exponential current source. Evaluation was done for standard inverters in IHP’s 130 nm CMOS process. The average relative error of the proposed model with respect to the results from SPICE simulations is below 10 % for analyzed cases.

This paper considers the design of robust logarithmic µ-law companding quantizers for the use in analog-to-digital converters in communication system receivers. The quantizers are designed for signals with the Gaussian distribution, since signals at the receivers of communication systems can be very well modeled by this type of distribution. Furthermore, linearization of the logarithmic µ-law companding function is performed to simplify hardware implementation of the quantizers. In order to reduce energy consumption, low-resolution quantizers are considered (up to 5 bits per sample). The main advantage of these quantizers is high robustness - they can provide approximately constant SNR in a wide range of signal power (this is very important since the signal power at receivers can vary in wide range, due to fading and other transmission effects). Using the logarithmic µ-law companding quantizers there is no need for using AGC (automatic gain control), which reduces the implementation complexity and increases the speed of the analog-to-digital converters (ADC) due to the absence of AGC delay. Numerical results show that the proposed model achieves good performances, better than a uniform quantizer, especially in a wide range of signal power. The proposed low-bit ADCs can be used in MIMO and 5G massive MIMO systems, where due to very high operating frequencies and a large number of receiving channels (and consequently a large number of ADCs), the reduction of ADC complexity and energy consumption becomes a significant goal.

DOI: 10.1109/TMTT.2019.2914104, (EMPHASE)
This paper presents a scalable E-band radar platform based on single-channel fully integrated transceivers (TRX) manufactured using 130-nm silicon–germanium (SiGe) BiCMOS technology. The TRX is suitable for flexible radar systems exploiting massive multiple-input-multiple-output (MIMO) techniques for multidimensional sensing. A fully integrated fractional-N phase-locked loop (PLL) comprising a 39.5-GHz voltage-controlled oscillator is used to generate wideband frequency-modulated continuous-wave (FMCW) chirp for E-band radar front ends. The TRX is equipped with a vector modulator (VM) for high-speed carrier modulation and beam-forming techniques. A single TRX achieves 19.2-dBm maximum output power and 27.5-dB total conversion gain with input-referred 1-dB compression point of −10 dBm. It consumes 220 mA from 3.3-V supply and occupies 3.96 mm2 silicon area. A two-channel radar platform based on full-custom TRXs and PLL was fabricated to demonstrate high-precision and high-resolution FMCW sensing. The radar enables up to 10-GHz frequency ramp generation in 74–84-GHz range, which results in 1.5-cm spatial resolution. Due to high output power, thus high signal-to-noise ratio (SNR), a ranging precision of 7.5 µm for a target at 2 m was achieved. The proposed architecture supports scalable multichannel applications for automotive FMCW using a single local oscillator (LO).

In this paper, we show our 165 Gbps data link layer processor for wireless communication in the terahertz band. The design utilizes interleaved Reed-Solomon codes with dedicated link adaptation, fragmentation, aggregation, and hybrid-automatic-repeat-request. The main advantage is the low chip area required to fabricate the processor, which is at least 2 times lower than the area of low-density parity-check decoders. Surprisingly, our solution loses only ~1 dB gain when compared to high-speed low-density parity-check decoders. Moreover, with only 2.38 pJ/bit of energy consumption at 0.8V, one of the best results in the class of comparable implementations has been achieved. Alongside, we show our vision of a complete 100 Gbps wireless transceiver, including radio frequency frontend and baseband processing. For the baseband realization, we propose parallel sequence spread spectrum and channel combining at the baseband level. Challenges to high-speed wireless transmission at the terahertz band are addressed as well. To the authors’ best knowledge, it is one of the first data link layer implementations that deal with a data rate of ≥100 Gbps.

IEEE Transactions on Wireless Communications 18(1), 340 (2019)
DOI: 10.1109/TWC.2018.2879661, (maximumMIMO)
In this paper, we show a novel algorithm for strong line-of-sight (LoS) multiple-input-multiple-output (MIMO) channel equalization. With optimally spaced antennas under specific arrangements, the LoS channels can be made spatially orthogonal. In practice, antenna displacements are expected. Conventional algorithms like zero-forcing (ZF) do not consider the special properties of the LoS MIMO channel and result in high complexity. We show that the LoS MIMO channel can be factorized into a product of three matrices. Thereby, the two diagonal matrices at the outer product positions are the most varying terms and should be compensated dynamically. Being a good tradeoff between complexity and robustness, the proposed sequential channel equalization is applied in a reverse order of the factorization. The algorithm can be applied to LoS MIMO systems with uniform linear or rectangular arrays, which are making use of digital or analog equalization. By considering the usage of the Winograd butterfly and Butler matrices, the number of multiplications in both digital and analog implementations of the proposed solution is increasing approximately linearly with respect to the number of antennas, while the complexity of the state-of-the-art designs grows quadratically. As found numerically and verified experimentally, the proposed method performs nearly as well as the ZF-based algorithms with near-optimal arrangements, while having significantly lower complexity.

DOI: 10.1109/CCWC.2019.8666546, (WORTECS)
Ultra wide-band terahertz (THz) radio links are envisaged for high throughput and low latency radio communication from server to virtual reality (VR) head mounted display (HMD). Orthogonal radio frequency (RF) beamforming is suitable for such extremely high frequency radio links owing to the propagation characteristics. For RF beam training, the transmit-receive (Tx-Rx) beam combination yielding maximum received signal strength indication (RSSI) is selected. For typical complex signals employed in IQ architecture receivers, RSSI is Rayleigh distributed. Receiver noise can cause false beam selections manifesting in communication rate loss. In this paper, analytically derived closed-form expressions and preliminary Monte Carlo (MC) simulation results for such noise performance evaluation have been presented.

In this paper, a SET pulse width model derived from SPICE simulations is presented. The model expresses the SET pulse width in terms of particle’s LET, target inverter’s drive strength and supply voltage. A bias-dependent current source was employed to model the SET current pulse, thus providing better accuracy compared to similar approaches based on the widely used double-exponential current source. Evaluation was done for standard inverters in IHP’s 130 nm CMOS process. The average relative error of the proposed model with respect to the results from SPICE simulations is below 10 % for analyzed cases.

This paper considers the design of robust logarithmic µ-law companding quantizers for the use in analog-to-digital converters in communication system receivers. The quantizers are designed for signals with the Gaussian distribution, since signals at the receivers of communication systems can be very well modeled by this type of distribution. Furthermore, linearization of the logarithmic µ-law companding function is performed to simplify hardware implementation of the quantizers. In order to reduce energy consumption, low-resolution quantizers are considered (up to 5 bits per sample). The main advantage of these quantizers is high robustness - they can provide approximately constant SNR in a wide range of signal power (this is very important since the signal power at receivers can vary in wide range, due to fading and other transmission effects). Using the logarithmic µ-law companding quantizers there is no need for using AGC (automatic gain control), which reduces the implementation complexity and increases the speed of the analog-to-digital converters (ADC) due to the absence of AGC delay. Numerical results show that the proposed model achieves good performances, better than a uniform quantizer, especially in a wide range of signal power. The proposed low-bit ADCs can be used in MIMO and 5G massive MIMO systems, where due to very high operating frequencies and a large number of receiving channels (and consequently a large number of ADCs), the reduction of ADC complexity and energy consumption becomes a significant goal.

This paper presents a scalable E-band radar platform based on single-channel fully integrated transceivers (TRX) manufactured using 130-nm silicon–germanium (SiGe) BiCMOS technology. The TRX is suitable for flexible radar systems exploiting massive multiple-input-multiple-output (MIMO) techniques for multidimensional sensing. A fully integrated fractional-N phase-locked loop (PLL) comprising a 39.5-GHz voltage-controlled oscillator is used to generate wideband frequency-modulated continuous-wave (FMCW) chirp for E-band radar front ends. The TRX is equipped with a vector modulator (VM) for high-speed carrier modulation and beam-forming techniques. A single TRX achieves 19.2-dBm maximum output power and 27.5-dB total conversion gain with input-referred 1-dB compression point of −10 dBm. It consumes 220 mA from 3.3-V supply and occupies 3.96 mm2 silicon area. A two-channel radar platform based on full-custom TRXs and PLL was fabricated to demonstrate high-precision and high-resolution FMCW sensing. The radar enables up to 10-GHz frequency ramp generation in 74–84-GHz range, which results in 1.5-cm spatial resolution. Due to high output power, thus high signal-to-noise ratio (SNR), a ranging precision of 7.5 µm for a target at 2 m was achieved. The proposed architecture supports scalable multichannel applications for automotive FMCW using a single local oscillator (LO).

In this paper, we show our 165 Gbps data link layer processor for wireless communication in the terahertz band. The design utilizes interleaved Reed-Solomon codes with dedicated link adaptation, fragmentation, aggregation, and hybrid-automatic-repeat-request. The main advantage is the low chip area required to fabricate the processor, which is at least 2 times lower than the area of low-density parity-check decoders. Surprisingly, our solution loses only ~1 dB gain when compared to high-speed low-density parity-check decoders. Moreover, with only 2.38 pJ/bit of energy consumption at 0.8V, one of the best results in the class of comparable implementations has been achieved. Alongside, we show our vision of a complete 100 Gbps wireless transceiver, including radio frequency frontend and baseband processing. For the baseband realization, we propose parallel sequence spread spectrum and channel combining at the baseband level. Challenges to high-speed wireless transmission at the terahertz band are addressed as well. To the authors’ best knowledge, it is one of the first data link layer implementations that deal with a data rate of ≥100 Gbps.

IEEE Transactions on Wireless Communications 18(1), 340 (2019)
DOI: 10.1109/TWC.2018.2879661, (maximumMIMO)
In this paper, we show a novel algorithm for strong line-of-sight (LoS) multiple-input-multiple-output (MIMO) channel equalization. With optimally spaced antennas under specific arrangements, the LoS channels can be made spatially orthogonal. In practice, antenna displacements are expected. Conventional algorithms like zero-forcing (ZF) do not consider the special properties of the LoS MIMO channel and result in high complexity. We show that the LoS MIMO channel can be factorized into a product of three matrices. Thereby, the two diagonal matrices at the outer product positions are the most varying terms and should be compensated dynamically. Being a good tradeoff between complexity and robustness, the proposed sequential channel equalization is applied in a reverse order of the factorization. The algorithm can be applied to LoS MIMO systems with uniform linear or rectangular arrays, which are making use of digital or analog equalization. By considering the usage of the Winograd butterfly and Butler matrices, the number of multiplications in both digital and analog implementations of the proposed solution is increasing approximately linearly with respect to the number of antennas, while the complexity of the state-of-the-art designs grows quadratically. As found numerically and verified experimentally, the proposed method performs nearly as well as the ZF-based algorithms with near-optimal arrangements, while having significantly lower complexity.

Ultra wide-band terahertz (THz) radio links are envisaged for high throughput and low latency radio communication from server to virtual reality (VR) head mounted display (HMD). Orthogonal radio frequency (RF) beamforming is suitable for such extremely high frequency radio links owing to the propagation characteristics. For RF beam training, the transmit-receive (Tx-Rx) beam combination yielding maximum received signal strength indication (RSSI) is selected. For typical complex signals employed in IQ architecture receivers, RSSI is Rayleigh distributed. Receiver noise can cause false beam selections manifesting in communication rate loss. In this paper, analytically derived closed-form expressions and preliminary Monte Carlo (MC) simulation results for such noise performance evaluation have been presented.
