Low power UWB pulse radio transceiver front-end

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....

Description
Summary: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 mm 2 , and data exchange rate of 8 Mbits/s with power consumption of 2.6 mw at 1.5 V
