Abstract
A single‐chip broadband CMOS receiver front‐end, integrating a low‐noise amplifier (LNA), a correlator, and a template pulse generator, was investigated in nonsinusoidal time‐domain environment for possible use as an impulse‐type ultra‐wideband (UWB) receiver front‐end. Particularly, the CMOS LNA and the multiplier making up the core component of the correlator were designed, fabricated, and tested to verify operation in the UWB range. Time‐domain results of the integrated CMOS receiver front‐end demonstrate its workability as a receiver for nonsinusoidal UWB applications. © 2009 Wiley Periodicals, Inc.
