Abstract
PURPOSE: To make a circuit suitable for integration by making it unnecessary that a large-capacity capacitor difficult to integrate is connected to the collector by defining the emitter side of a transistor as a refernce power source to make the collector-side impedance small.
CONSTITUTION: In respect to signals applied to input terminal 20, signals having a level over a prescribed level in the positive direction as well as the negative direction are supplied to resistances 23 and 24 through capacitor 22. Diode 25 determines the upper limit voltage to be clipped, and diode 28 determines the lower limit voltage. Center value V0 between the upper limit value and the lower limit value of the clip voltage is indicated by the half of voltage VA of control power source 31 by equalizing values of resistances 23, 24, 26 and 29 to one another and equalizing base.emitter voltage VBE2 of transistor 27 and voltage VF3 dependent upon diode 30 to each other approximately and is independent of temperatures.
