Abstract
A low quiescent power class AB current mirror circuit includes a first input transistor for receiving an input current and a second output transistor for providing an output current; the first and second transistors having bases connected together; and a first current supply for sinking current from the bases in response to a decrease in input current to lower the quiescent point of the transistors.
