Based on zero-IF receiver architecture, the front end comprises a variable gain common-source low noise amplifier with an on-chip transformer as its load and a high linear quadrature folded Gilbert mixer. As the load of the LNA, the on-chip transformer is optimized for lowest resistive loss and highest power gain. The whole front end draws 21 mA from 1.2 V supply, and the measured results show a double side band noise figure of 3.75 dB, -31 dBm IIP3 with 44 dB conversion gain at maximum gain setting. Implemented in 0.13 μ m CMOS technology, it occupies a 0.612 mm2 die size. %K zero-IF %K direct-down-conversion %K WLAN %K CMOS %K RF %K on-chip %K transformer %U http://www.alljournals.cn/get_abstract_url.aspx?pcid=5B3AB970F71A803DEACDC0559115BFCF0A068CD97DD29835&cid=1319827C0C74AAE8D654BEA21B7F54D3&jid=025C8057C4D37C4BA0041DC7DE7C758F&aid=C6D3D1CB1D1B4FDF0B31C323EF2CF11F&yid=9377ED8094509821&vid=9971A5E270697F23&iid=59906B3B2830C2C5&sid=854038CE6065526E&eid=B31275AF3241DB2D&journal_id=1674-4926&journal_name=半导体学报&referenced_num=0&reference_num=9
