Abstract
A so-called 'V.sub.BE multiplier' circuit is used to temperature compensate a semiconductor device with respect to both short term self-heating effects and long term ambient temperature effects. The compensation circuit includes a transistor with a base, an emitter coupled to an operating potential, and a collector coupled to an operating potential. First and second resistors are respectively coupled across the base-emitter and collector-base junctions of the transistor. The values of the resistors as chosen so that a voltage derived from the collector-emitter path of the transistor and applied to the semiconductor device exhibits a temperature coefficient which substantially matches the temperature coefficient of the semiconductor device.
