Abstract

A four-quadrant analog signal multiplier circuit with a folded cascode differential input stage allows such circuit to be operated at lower power supply voltage potentials, while allowing the same transistor types to be used for both sets of input signals thereby providing for more closely matched input device characteristics and signal gains.
