摘要
A Darlington output stage is shown in which the saturation voltage is reduced to the level of a single common emitter output transistor (13). The circuit includes a lateral feed-forward transistor (21) that bridges the driver transistor (14). A resistor (20) is included to ensure that the driver transistor (14) is turned off when the output transistor (13) saturates. An IC version of the circuit is set forth in detail.
