A study on theoretical representation of intermodulation in CMOS balanced mixers

Intermodulation of CMOS balanced mixers is analyzed in this paper with the aim of reducing the effects of intermodulation distortion into a set of simple equations. The analysis consists of a theoretical study and simulation results. Analysis and simulations results reveal that the mechanism of intermodulation in balanced mixers is too complex to be represented by simple equations. Numerical methods must be used to predict the effects of intermodulation in balanced mixers.
