摘要:
A system providing a drive circuit for a bipolar transistor high in speed and low in power consumption even under a low source voltage using a MOSFET is disclosed. The base current of the bipolar transistor is supplied not by short-circuiting the collector and the base thereof by a MOSFET but from another base current source.
