Abstract
Systems and methods for adjusting threshold voltage. A threshold voltage of a transistor of an integrated circuit is measured. A bias voltage, which when applied to a body well of the transistor corrects a difference between the threshold voltage and a desired threshold voltage for the transistor, is determined. The bias voltage is encoded into non-volatile storage on the integrated circuit. The non-volatile storage can be digital and/or analog.
