ABSTRACT:
A current mirror amplifier includes first and second transistors connected together at their common electrodes, the first transistor being connected for receiving input signal current at its output electrode, and the control electrodes of the transistors being connected for conditioning the second transistor for conducting a current responsive to the input signal current. Switch means, responsive to a control signal, selectively connects the output electrode of the second transistor to a supply terminal so the current gain between the input signal current and the current in the connection of their common electrodes switches responsive to the control signal.
