ABSTRACT:
To compensate for process, activity and temperature-induced device threshold variations in a semiconductor circuit having a transistor, a potential of the gate the transistor is held to a preset subthreshold potential, and a channel current of the channel region is compared with a reference current to obtain a comparison result. A bias potential of a substrate is adjusted according to the comparison result to hold the subthreshold current at the reference current.
