Abstract
A circuit for temperature compensating the inverse saturation current of a bipolar transistor having a collector region, base and emitter regions defining a base-emitter junction is disclosed. A diode element having substantially said same saturation current is parallel-connected in reverse configuration to said base-emitter junction of the bipolar transistor. If the bipolar transistor is NPN type, the diode has an anode and cathode connected respective to the emitter and base regions of the transistor.
