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.
