Abstract:
     A frequency mixing consists of frequency mixing module for mixing the first set of differential signal with the second set of differential signal to generate a mixed signal , a common – mode voltage generator coupled with frequency mixing module for detecting common – mode voltage of frequency mixing module , and a compensating module coupled to common – mode generator and frequency mixing module for compensating operational point offset of multiple conversion transistors in frequency mixing module according to common – mode voltage .
