METHOD AND SYSTEM FOR ADAPTIVE POWER MANAGEMENT

摘要

A system comprises an integrated circuit comprising one or more transistors that receive a supply voltage. The system also includes a reference transistor operable to receive a constant current and produce a reference voltage that varies according to temperature or process variations, wherein the reference transistor behaves similarly to at least one of the one or more transistors with respect to temperature or process variations. The system also includes a comparator operable to compare the reference voltage with the received supply voltage and produce an output based at least in part on the difference between the reference voltage and the received supply voltage. The system further includes a controller operable to adjust the received supply voltage based at least in part on the output of the comparator.
