THE DESIGN OF INTEGRATED 0.13-mu m CMOS RECEIVER FOR ULTRA-WIDEBAND SYSTEMS

Abstract

A fully integrated 0.13-mu m CMOS receiver for ultra-wideband systems is implemented. This receiver enables eight bands of operation covering 3.1-9.0 GHz. The system, based on the Multiband OFDM Alliance standard proposal and consisting of a direct-conversion receiver chain and required noise figure, is discussed. The average conversion gain and input PldB are 67.3 dB and -25.4 dBm, respectively. The shunt-series feedback low-noise amplifier provides a receiver front-end noise figure of 7.1-9.5 dB over the entire band. The mixer, based on a folded-cascode topology, also implements a four-stage programmable gain amplifier. A fabricated die has been bonded and molded onto PCB for characterization. The receiver chip dissipates 48 mA from 1.2V power supply. (C) 2010 Wiley Periodicals. Inc.
