The balanced, differential-amplifier configuration finds wide applicability in its monolithic integrated form. This paper investigates the use of the MIC differential amplifier as a mixer. The device chosen for this investigation permits signal injection both in the differentially driven pair and in the constant-current sink which biases the differential pair. Device characteristics pertinent to the mixing process are generated and discussed. On the basis of the experimentally derived characteristics, several different frequency conversion methods are employed and compared on the basis of conversion gain and distortion and intermodulation effects.
