摘要：

This paper presents a baseband processor for pulsed ultra-wideband signals. It consists of an analog to digital converter (ADC), a clock generation system and a digital back-end. The FLASH interleaved ADC provides four bit samples at 1.2GSPS. The back-end uses parallelization to process these samples and to reduce the signal acquisition time to 70mus. The baseband processor was implemented in the same 0.18mum CMOS chip as a part of a complete transceiver. A complete 193kbps wireless link is demonstrated.
