ABSTRACT:
There is disclosed an adaptive voltage power supply that finely adjusts VDD to an optimum level. The adaptive voltage power supply comprises: 1) a first charging circuit capable of increasing a reference voltage on a charge capacitor in response to receipt of a first VDD control signal; 2) a second charging circuit capable of decreasing the reference voltage on the charge capacitor in response to receipt of a second VDD control signal; and 3) a power supply capable of receiving the reference voltage on the charge capacitor and generating an output power level, VDD, determined by a level of the reference voltage.
