摘要：

A low flicker-noise CMOS mixer for multi-standard receiver in 130-nm CMOS is presented. The mixer which consists of an AC coupled passive mixer and a low noise buffer amplifier with CMFB achieves a low flicker noise corner frequency of 50 kHz. Dual-mode DC offset cancellation circuits are used to compensate the mixer DC offset for multi-standard communications. It provides conversion gain of 13.2 dB, IIP3 of 4.5 dBm, DSB NF of 12.3 dB@100 kHz, white DSB NF of 11 dB, and output DC offset of less than 0.5 mV This mixer consumes 5.5 mA at a supply voltage of 1.5 V.
