ABSTRACT:
A system and method for adaptively providing a power supply voltage. The system includes an oscillator configured to receive an output voltage and generate a firs signal. The first signal is associated with a first frequency and a first period. Additionally, the system includes a frequency comparator configured to receive the first signal associated with the first frequency and a second signal associated with a second frequency and to generate a third signal if the first frequency and the second frequency are not equal, and a voltage regulator coupled to the frequency comparator and configured to generate the output voltage based on at least information associated with the third signal. The output voltage is received by a powered system, and the powered system is configured to receive a clock signal associated with a clock frequency. The clock frequency is equal to the second frequency.
