摘要：
A high-gain low-noise CMOS downconversion active folded mixer which can operate at 900mV supply voltageis presented in this paper, and a LC circuit is introduced between the common source node of the switching pair to resonate out the parasitic capacitance in order to improve the performance. The mixer is designed in chartered 0.18-mu m one-poly six-metal CMOS technology for 2.4GHz ISM band applications. With an input 2.44GHz RF signal of -50dBm driven by a 2.442GHz LO signal of 0dBm, simulation results show that the conversion gain is 18.6 dB, the input/output-referred third-order intercept point are -8.77/9.88dBm respectively, and the single-sideband noise figure is 7.15 dB. The power consumption of the mixer is 5.2mW.
