Abstract
Circuitry and method for compensating for the junction leakage current of a reverse-biased semiconductor device. Compensation is effected by trimming the leakage of a compensating device at a high temperature in order to accurately compensate the leakage current over a broad range of temperatures. Potential applications include reduction of the input bias current of an amplifier or differential amplifier.
