ABSTRACT:
A pair of transistors are operated at different current densities so as to develop a differential base to emitter potential. This potential is used as a reference in a negative feedback stabilization circuit which passes a current that is regulated by the potential. The circuit can also regulate the currents flowing in a plurality of additional current sources and sinks connected thereto.
