A low power noncoherent CMOS UWB transceiver ICs

Abstract

A fully integrated pulse based UWB transmitter and receiver (TRX) using a novel and simple noncoherent architecture is presented. Fabricated in a 0.18/spl mu/m CMOS process, the signal from the transmitter is binary amplitude modulated pulses and meets FCC UWB low frequency band (3.1-5 GHz) specification. The receiver archives a noise figure of 7.5 dB, IIP3 of -14 dBm, and sensitivity of -72 dBm. The TRX can attain a transmission rate up to 50 Mbps without synchronization circuits and consumes 41.4 mW average power.
