A method and apparatus for compensating a base current of a bipolar junction transistor by replicating operating conditions of the BJT in a compensating circuit. An output current of the compensating circuit is fractionally related to the base current and thus can be supplied to an operational circuit comprising the BJT to compensate the base current. In a preferred embodiment, the BJT is operated between BVCEO and BVCBO and the base current to be compensated flows from the BJT.
