ABSTRACT:
Compensation for the current flowing in the collector resistance of a transistor is achieved by generating a compensating current of appropriate magnitude and polarity sense, and applying that compensating current to the base of the transistor. To this end, a voltage equivalent to that across the transistor emitter-collector path is applied across a current conductive device representative of the collector resistance. The current therethrough is then proportioned by a current amplifier and applied to the base of the transistor to be compensated.
