Abstract

A novel CMOS active mixer topology that can operate at low voltages (e.g. 1 v) is presented in this paper. By switching the load on or off other than switching the current, the switches require no voltage headroom. Because the switches are capacitively connected to the load, the switch can operate under full swing allowed by the supply voltage and contribute no thermal noise. The mixer is designed in 0.18 um CMOS technology, and the simulation results at 1 V supply voltage are satisfactory (gain=7 dB, IP3=7 dBm, NF-11 dB).
