Abstract
A substrate bias control circuit includes a process voltage temperature (PVT) effect transducer that responds to a PVT effect. A PVT effect quantifier is coupled to the PVT effect transducer. The PVT effect quantifier quantifies the PVT effect to provide an output. The PVT effect quantifier includes at least one counter and a period generator. The period generator provides a time period for the counter. A bias controller that is coupled to PVT effect quantifier is configured to receive the output of the PVT effect quantifier. The bias controller is configured to provide a bias voltage. The bias controller includes a bias voltage comparator.
