Abstract

This paper describes the design and performance of a 90 nm CMOS SA W-less receiver with DigRF interface that sup- ports 10 WCDMA bands (I, II, III, IV , V , VI, VIII, IX, X, XI) and 4 GSM bands (GSM850, EGSM900, DCS1800, PCS1900). The re- ceiver is part of a single-chip SA W-less transceiver reference plat- form IC for mass-market smartphones, which has been designed to meet Category 10 HSDPA (High Speed Downlink Packet Ac- cess) requirements. The novel receiver core consists of a single- stage
