Abstract
An amplifier circuit, having voltage gain responsive to a control signal, includes a transistor stage having a transistor and a load, and an amplifier stage in cascade connection, and a control transistor connected to the transistor. The control signal varies the collector current of the transistor via the control transistor whereby the voltage gain of the transistor stage correspondingly varies. Degenerative feedback couples the output to the input for stabilizing the quiescent output potential so that the amplifier circuit is susceptible of being direct coupled to subsequent circuits.
