Abstract:
A mixer for downconversion of RF signals includes at least one RF transistor (305); at least one switching pair (303) connected to the drain current (301) of the at least one RF transistor (305); and a common mode sensing component (300) configured to detect deviations in the common mode output of the switching pair (303) from a specified output; wherein the deviations modify the current of the at least one switching pair (303).
