A CMOS active mixer based on variable load technique which can operate at 1.0V supply voltage is proposed and its operation principle is presented. The proposed mixer controls the load impedance according to the LO signal. It has only two stacked transistors at each branch, which is suitable for low-voltage applications. The mixer was designed in 0.18-μm(More)
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)
