Energy-Efficient RF Front-end Architectures for Large-Scale Sensor Networks

This component project of the CIDR aims to explore asymmetric radio frequency (RF) circuit topologies and system architectures for very low-power wireless sensor nodes running purely on harvested energy. By combining impulse radio (IR) ultra-wideband (UWB) transmitters (Tx) with on-off keying (OOK) energy detection receivers (Rx), we expect significant reduction in the overall energy requirements of the entire radio front-end transceiver (TxRx). This would potentially enable a wide variety of sensor and internet-of-things (IoT) applications in severely energy-starved environments.

Activities

The project will have three major activities:

  1. The development of IR-UWB transmitter system models for analysis, energy optimization, and automated circuit generation,
  2. The design, implementation, and verification of IR-UWB transmitter building blocks, and
  3. The design, implementation, and verification of a proof-of-concept IR-UWB transmitter, all in 22nm fully-depleted silicon-on-insulator (FDSOI) CMOS technology.
