Abstract :
This paper presents a low power CMOS down sampling micromixer in 65nm with an improved input stage. It is able to handle a superimposed DC current on the input port without degrading circuit performance. The mixer was fabricated in a triple-well process. A conversion gain of 17dB is achieved while only consuming 780muW from a 1.2V voltage supply up to a 3dB clock frequency of 600MHz. The gain decreases for 3dB at a superimposed DC current of 210muA. The 1dB compression point and IIP3 are measured to be -22.7dBm and -16dBm, respectively.
