ABSTRACT:
A circuit suitable for providing constant current bias for I.C's includes two transistors arranged to pass current in parallel in which base emitter voltage applied to one transistor is derived from the base emitter voltage applied to the other transistor with the base emitter voltage applied to the one transistor reduced by a component proportional to the magnitude of the current passed by the other transistor.
