Abstract

A low-voltage and low-power RF mixer for WCDMA ap plications is presented. The paper presents a novel topology mixer that leads to a better performance in terms of isolation and power consumption for low supply voltage. The measuring results of the proposed mixer achiese: 7dB power conversion gain, 10.4 dB double side band (DSB) noise figure, -2 dBm input third-order intercept point (11P3), and the total dc power consumption of this mixer including output buffers is 2.2mW from a 1 V supply voltage. The current output buffer is about 1.96 mW, the excellent LO-RF, LO-IF and RF-IF isolation achieved up to 49dB, 39.5dB and 57.3 dB, respectively. .
