Abstract

PURPOSE: To secure elimination of the DC fluctuation caused by the saturation voltage between the collector and the emitter of the transistor by giving the conduction in other half-cycle of the rectangular wave to the transistors which are in the complementary relation.
CONSTITUTION: PNP transistor Tr17 is turned on in the half cycle period of rectangular wave 10 applied to input terminal 1, and capacitor C8 is charged up to power voltage +E as shown by arrow 20. Thus, the value of voltage E3 is obtained. This value shows the amount added with the effect caused by the leak voltage between the emitter and the collector of Tr17. Then Tr17 is turned off in the other half cycle with PNPTr4 turned on, and accordingly the electric charge in C8 is discharged as shown by arrow 21 to obtain voltage E2. In this case, it is supposed that Tr17 and 4 feature the identical ambient temperatures. As a result, the saturation voltage between the collector and the emitter is substantially identical between Tr17 and 4 thus to obtain E2=E3, and accordingly the DC-changed output level never change with every half cycle of the rectangular wave.
