Abstract

This paper presents an integrated UWB shortrange impulse radar implemented in a 130 nm CMOS process. The transmitter can digitally generate various waveforms with up to 10 GHz bandwidth at 5 dBm peak power. The receiver utilizes a time interleaved scheme to support a 20 GS/s effective sampling rate. Sample-domain averaging of multiple identical received waveforms reduces the required digitization rate and corresponding power consumption. Sampling clocks for the time interleaved samplers are generated using independent delay locked loops that are locked to the same reference. Measurement results of the individual blocks as well as the entire system are presented.
