摘要：
This paper introduces a low voltage, low power down-conversion mixerbased on 0.18. m RF CMOS process, the transconductance stage of which uses the current-reuse. The mixer is composed of two identical mixers which share the same transconductance stage, folded switching stage, active load stage, and common-mode feedback (CMFB) circuits. The mixer hassome advantages of low supply voltage, high conversion gain, and low noise figure. The post-simulation results show that, with a power supply voltage of 1V and a input RF frequency of 802 MHz, the mixer achieves a conversion gain (CG) of 10.7dB, the singleside-band (SSB) noise figure (NF) is 7.969dB, the input 1dB compression point (IP1dB) of -15.57dBm, the third-order input intercept point (IIP3) is -5.16dBm, and the current consumption is merely 357.1 mu A.Phi
