Abstract A D.C. gain controlled differential amplifier exhibiting balanced operation and a linear gain control response. The amplifier includes input and output emitter coupled transistors and a current source transistor. Input signals are supplied to the base of the input tran- sistor, and a negative feedback network is D.C. coupled from the collector to base of the output transistor. A D.C. gain control voltage varies the conduction of the current source transistor to thereby vary the gain of the emitter coupled transistors. The control voltage is also D.C. coupled to a collector signal output of the output transistor to maintain the output quiescent level substantially constant as the amplifier is gain controlled.
