Abstract
PURPOSE:To avoid output distortion, by applying an emitter output of a PNP transistor (TR) to an input stage of an inphase amplifier and a collector output of an NPN TR to an input stage of an inverting amplifier. CONSTITUTION:An audio signal is inputted to amplifiers AmpIand AmpII from a terminal (1) via TRsQ1, Q2. Output signals V01, V02 at terminals (5), (6) become output signals including equal phase lead components by an input capacitor C1, input impedance Zi viewed from the terminal (1), AC by-pass capacitors C2, C3 at a feedback terminal and feedback resistors R2, R102. Thus, a synthesized output without distortion due to phase difference between the output signal V01 of the amplifier AmpIand the output signal V02 of the amplifier AmpII can be obtained across the load resistor RL.
