ABSTRACT:
A transistor output stage including an output transistor having its base coupled to the emitter of a driver transistor is driven into saturation by a current source which is connected to the base of the driver transistor. When a small output current is flowing through the load connected to the collector of the output transistor, the surplus of the current from the current source is drained from the base of the driver transistor to the collector of the output transistor via the collector-emitter path of a limiting transistor having its base connected to the base of the output transistor. This reduces the power dissipation in the driver transistor and improves the power efficiency of the transistor output stage.
