Abstract
PURPOSE:To reduce power consumption providing a transistor on which collecter cut-off current almost equivalent to that of a Darlington-connected transistor flows. CONSTITUTION:The collector of the transistor Q7 is connected to the emitter of the transistor Q2 at a first stage out of the transistors Q2-Q4 which constitute Darlington connection. Consequently, the collector cut-off current of the transistor Q2 flows between the collector and the emitter of the transistor Q7, and it is offset by the collector cut-off current of the transistor Q7. In such a way, since the current can be offset without transmitting the collector cut-off current of the Darlington-connected transistor, it is not required to permit surplus reactive current to flow on the constant current source of the transistor at the final stage, thereby, the power consumption can be reduced.
