A High Gain Low Noise Mixer With Cross-Coupled Bleeding

A mixer implementing a cross-coupled bleeding circuit for improved conversion gain and noise performance is reported. The proposed mixer is implemented in 0.18
$\mu{\rm m}$
CMOS technology. The measured results show a 17 dB conversion gain,
${- 4.7}~{\rm dBm}$
IIP3 for an RF signal frequency of 765 MHz, 7.9 dB noise figure, and 125 kHz flicker noise corner while consuming 3.12 mA from a 1.8 V supply.
