ABSTRACT:
A current, produced by a differential amplifier and proportional to a reference voltage and/or a reference value, is compensated for variation of the base-emitter voltage and of the current gain factor over a comparatively large control range, in that the common-emitter current of the differential amplifier is controlled proportionally to the output current with the aid of current mirror circuits.
