3.1-to-7GHz UWB impulse radio transceiver front-end based on statistical correlation technique

This paper presents the UWB impulse radio transceiver front-end based on statistical correlation technique between multiple band-pass filters tuned within UWB spectrum. The band-pass filters can detect energy either from transmitted UWB impulses, interfering channels or noise. Transmitted UWB impulses can be extracted by statistical correlation in between the outputs of band-pass filters. Super-regenerative receivers, tuned within 3.1-to-7 GHz 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 1.44 mm², sensitivity of -99 dBm and -30 dB SIR with power consumption of 15 mW at 1.5 V.
