Abstract

A 1.9-GHz down-conversion CMOS mixer, intended for the GSM1900 (PCS1900) Low-IF receivers is present with the utilization of novel folded Gilbert Cell fabricated in a RF 0.18-μm CMOS process. The prototype demonstrates a good performance. It achieves a conversion gain of 6dB, SSB Noise Figure of 18.5dB and IIP3 11.5dBm while consuming 7mA current from 3.3V power supply.
