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.
Claims12
A method of encoding threshold voltage adjustments for an integrated circuit, said method comprising:
- measuring a threshold voltage of a transistor of said integrated circuit;
- determining a bias voltage which when applied to a body well of said transistor corrects a difference between said threshold voltage and a desired threshold voltage for said transistor;
- and
- encoding said bias voltage into non-volatile storage on said integrated circuit.
