Ultra-Low Power Circuits

Main Fields

  • Wake-up receivers
  • Short-range radio transceivers for wireless sensor network applications
  • Ultra-wide band (UWB) transceivers for communication, localization and radar applications
  • Analogue circuits for sensors

Main focus

This group focusses on developments to minimize the DC power dissipation of fully integrated radio transceivers while ensuring the demanded minimum performance. In many wireless sensor network nodes the power dissipation of the radio dominates the entire dissipation. In order to extend the battery lifetime of such nodes the research looks for advanced RF circuits as well as intelligent co-design with baseband processors and communication protocol implementation. Here, the introduction of sophisticated sleep-modes is targeted. 

Main Achievements

Recently, two different Impulse-Radio-UWB transceivers have been developed, intended for short range data communication as well as indoor localization applications. They are compliant with the ECC regulation in Europe and they are all equipped with sleep-mode capabilities to reduce the average power consumption while ensuring full functionality. One transceiver is conform to the IEEE standard 802.15.4a, supports all 4 RF channels in the higher UWB band between 6.0 and 8.5 GHz, and allows data rates from 0.85 Mbit/s to 27.24 Mbit/s. The second IR-UWB transceiver follows a proprietary communication scheme intended for high precision ranging (better 10 cm) as well as radar applications.
