Abstract

Mixer is an essential component for a communication system. Kinds of resolutions aiming at the improvement of mixer performance have been studied so far. In this paper, a fully differential structure is introduced and used in the design of a mixer with high linearity in a 0.18 μm CMOS RF process. Simulation results show that the input referred P_ldB (IP_ldB)of the mixer is 2.9 dBm, the input referred IP3 (IIP3) is 16 dBm and the power gain is 0.4 dB with a power consumption of 7.2 mW.
