Abstract :
In this paper, a new highly linear high-frequency CMOS mixer is presented. The new mixer is derived from the basic Gilbert multiplier. It achieves an outstanding linearity since the new topology does not contain any tail current branches. Simulation of the extracted layout results show a high linearity improvement over the basic Gilbert mixer, with HP3 of 31 dBm in 0.8 μm and 20 dBm in 0.18 μm. The new mixer´s test chip layout and its extracted simulation characteristics in both technologies are also presented.
