An Implementation of a CMOS Down-Conversion Mixer for GSM1900 Receivers
-
Abstract
A 1.9GHz down-conversion CMOS mixer with a novel folded Gilbert cell,intended for use in GSM1900(PCS1900) low-IF receivers,is fabricated in a RF 0.18μm CMOS process.The prototype demonstrates good performance at an intermediate frequency of 100kHz.It achieves a conversion gain of 6dB,SSB noise figure of 18.5dB (1MHz IF),and IIP3 11.5dBm while consuming a 7mA current from a 3.3V power supply.-
