IPC: H03F3/30
Filed: 1980-01-31
Abstract: PURPOSE: To avoid the switching distortion that is caused during a large output of an amplifying circuit, by applying the voltage fluctuation component of a power supply terminal to a variable bias generating circuit for output transistor.  
     CONSTITUTION: The driver transistors Q 3  and Q 4  are connected to the output transistors Q 1  and Q 2  each to form an SEPP circuit. Usually an equal potential is kept between the points X and Z, and the transistors Q 1  and Q 2  are at the active region to prevent the switching distortion. The collector current of the transistor Q 8  increases during a large output, and thus the collector current decreases for the transistor Q 5 . The voltage of the power supply terminal B 1  varies according to the current flowing to the output transistor, and this fluctuation component reduces the base potential of the transistors Q 8  and Q 9 . As a result, an equal potential can be kept between the points X and Z.
