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 PldB (IPldB)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.
