Fangqing Chu, Wei Li, Junyan Ren · Asia and South Pacific Conference on Design Automation, 2006. · 2006
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 an RF 0.18-/spl mu/m 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.
