Abstract :
A 900 MHz balanced harmonic mixer for direct conversion receivers is fabricated in a 0.35 μm standard digital CMOS process. The self-mixing-induced DC offset is about 44 dB lower than that of the conventional mixer. The input referred offset is reduced to the noise level. Specific techniques on flicker noise reduction are also discussed. At 3 V power supply and -15.4 dBm LO power, it achieves 13 dB conversion gain, 24.5 dB noise figure at 10 kHz, -10 dBm third-order input intercept point and +36 dBm second-order input intercept point. The total power consumption is about 5 mW
