Abstract
This paper describes a 1.5-V 2 GHz I/Q down conversion mixer for a WCDMA front-end receiver in a 0.18-mum CMOS process. The mixer achieves a conversion gain of 20.55 dB within 1-dB compression point (iCP1dB) of -9.2 dBm. It also achieves a double side band (DSB) noise figure (NF) of 8.96 dB. The mixer acquires the third order input referred intercept point (IIP3) of -0.54 dBm. The mixer consumes only 4.0 mA of current from a 1.5-V power supply
