This paper describes a carrier-based multi-band UWB transceiver front-end in CMOS 90nm designed for full UWB band biomedical radar sensing and sensor node communications. The transceiver operates in band 3-10GHz. The transceiver consists of a transmitter and a receiver. The transmitter includes a pulse generator, a mixer, a VCO, and a driver amplifier. The receiver includes a filter bank, a ultra wideband LNAs, mixers, integrators, and decision-making circuits. The system was simulated using CMOS 90nm technology to verify functions for both the sensor communications and radar sensing. The overall power consumption is 62.75mW.
