Abstract: PURPOSE:To surely obtain a circuit obtaining a low output impedance with excellent response by connecting a 2nd amplifier circuit of the similar circuit to a 1st amplifier circuit to the post-stage of the 1st amplifier circuit whose output impedance is low at the time of electrifying and providing a bypass element bypassing an output signal at the time of electrifying the 1st amplifier circuit to the 2nd amplifier circuit. CONSTITUTION:The titled circuit consists of a PNP transistor (TR) Q10 of common emitter type constituting the 1st amplifier circuit, a PNP TR Q11 of common collector type connected to the collector of the TR Q10 and constituting the 2nd amplifier circuit, and a diode D10 bypassing an output signal of the TR Q10 to the TR Q11 at the time of electrifying the TR Q10. In providing a low level signal to the base of the TR Q10 through a resistor 10, the TR Q10 is made conductive and the TR Q11 is made nonconductive. In such time, the diode D10 is made conductive and a high level signal is outputted at the output terminal A. In providing a high level signal to the base of the TR Q10, a low level signal is outputted at the output terminal. Thus, even with the input signal change as a bipolar pulse or at any polarity, the output impedance is surely lowered with excellent response.
