ABSTRACT:
An opposite-phase current source is improved by eliminating the conventionally employed current mirror circuits, and by instead using a pair of transistor current sources subjected to voltage feedback and emitter-connected via a resistor. A constant current source or sources are coupled to the opposite ends of the resistor or to a mid-point thereof.
