ABSTRACT:
A high gain integrated circuit amplifier is arranged in the form of a pair of cascaded common emitter stages. A current mirror is employed to track the stage currents. A high gain d-c negative feedback loop is employed to stabilize the amplifier, and each stage employs emitter diode degeneration to control gain as a function of current. Gain control is obtained by sinking current at a single node in one stage.
