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.
