Abstract
PURPOSE: Both NPN transistor's differential amplifier circuit and PNP transistor's differential amplifier circuit are connected to a complementary differential amplifier circuit. Thus, a low-distortion circuit can be obtained, through which the voltage between base of both differential amplification pair can be changed symmetrically to ground voltage.
