ABSTRACT:
In a broadcast receiver, a dc voltage operating source is coupled to an operating voltage terminal of a sound IF integrated circuit via a collector/emitter path of a transistor, and a second source of operating voltage is connected via an RC integrating network to the base of the transistor, with the base of the transistor being connected to ground via a zener diode.
