Low power inductor-less pulse UWB transceiver

This paper presents a new trigger receiving algorithm of the pulse UWB signal, aimed at eliminating the high requirement of process variation as well as the dependence on ultra-high sampling rate and circuit operating speed in conventional correlation receiving algorithm. This algorithm can reduce both circuit complexity and power consumption largely. Based on the proposed receiving algorithm, a fully integrated low power inductor-less pulse UWB transceiver is designed and fabricated in HJTC 0.18µm CMOS process with a total size of 0.45 mm2. The experimental results show that the total power consumption of the transceiver is only 7.2mW at 42Mb/s data rate from a 1.8V supply.
