ABSTRACT:
A mixing circuit for combining biasing and signals using a selectively variable signal gain which is independent of the biasing and using biasing which is independent of the selectively variable signal gain. A Gilbert cell is used to multiply a differential control voltage, which represents a normalized signal gain factor, with input currents which include biasing components and input signal components. The resultant output current includes a bias component which is independent of the differential control voltage and a signal component which is independent of the input current biasing components. The gain factor has a value between zero and unity which varies in relation to the differential input control voltage.
