Abstract:
A shunt regulated push-pull circuit comprising:a first transistor; a resistor through which a collector of said first transistor is connected to a first reference potential; a second transistor having a same polarity as said first transistor, a collector of said second transistor being connected to an emitter of said first transistor, and an emitter of said second transistor being connected to a second reference potential; and a third transistor having a polarity opposite a polarity of said first transistor, an emitter of said third transistor being connected to the collector of said first transistor and a collector of said third transistor being connected to a base of said second transistor, and a bias voltage being supplied to a base of said third transistor; wherein an input signal is supplied to a base of said first transistor, and an output signal is extracted from a node of the emitter of said first transistor and the collector of said second transistor.
