Low power UWB pulse radio transceiver front-end

Abstract

In this paper, we propose a low power architecture to extract UWB pulse radio signals from noise level in the presence of narrow band interfering channels. The receiver consists of many narrow band-pass filters, which extract energy either from transmitted UWB signal, interfering channels or noise. Transmitted UWB data can be extracted by statistical correlation of multiple band-pass filter outputs. Super-regenerative receivers, tuned within UWB spectrum, act as band-pass filters. Summer and comparator perform statistical correlation. The test structure of transceiver has been implemented on 0.18 mum CMOS technology, active area of 3.15 mm2, and data exchange rate of 8 Mbits/s with power consumption of 2.6 mw at 1.5 V
