Abstract

PURPOSE: To eliminate distortion generated in the voltage between the base and the emitter, by combining PNP and NPN transistors.
CONSTITUTION: Transistors TRs Q5 and Q6 constitute a current Miller circuit and flow a current, which is α times as high as the current flowed to a series circuit including a TR Q1, to a series circuit including a TR Q2, TR Q1 and Q2 and TRs Q3 and Q4 have polarities opposite to each other, and voltages between respective bases and emitters of TRs Q1 and Q2 and between TRs Q3 and Q4 are equal to each other respectively by the relation between a current I1 flowed to the TR Q1 and voltages between bases and emitters of respective transistors and the relational expression between emitter currents and voltages between bases and emitters which is satisfied generally, and consequently, the current I1 is not influenced by the voltage between the base and the emitter of the transistor.
