ABSTRACT:
A self-oscillating, push-pull inverter circuit is described wherein positive feedback signals are provided alternately to the bases of a pair of switching transistors by a single miniature saturable current transformer. The circuit performance relies on a pair of diodes having special characteristics connected across the base-emitter junctions of the respective switching transistors.
