Abstract

PURPOSE:To stabilize the output voltage by detecting the base current of the transistor connected to the amplifying transistor and then giving the control to the base current of the amplifying transistor. CONSTITUTION:TR8 is connected between the collector for transistor TR1 with signal source 5 connected to the base and collector power source 7; and at the same time base current detecting circuit 9 is connected to the base circuit of TR8. Furthermore, output terminal 10 of circuit 9 is connected to the base of TR1. In such circuit constitution, the control is given to the base of TR1 from terminal 10 of circuit 9 which detects the base current of TR8. As a result, the drop of the output voltage due to the fluctuation of the current amplification factor of the transistor or the resistance can be prevented, thus obtaining the stabilized output voltage.
