ABSTRACT:
A system for improving the power efficiency of an electronic device includes a threshold voltage selector and a supply voltage selector. The threshold voltage selector selects a value of a threshold voltage for operation of the device in response to a present operating condition of the device. The supply voltage selector selects a value of a supply voltage to be applied to the device in response to the present operating condition of the device. The value of the threshold voltage and the value of the supply voltage control a power consumption of the device.
