A high-gain low-noise CMOS downconversion active folded mixer which can operate at 900 mV supply voltage is 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-mum one-poly six-metal(More)
