Abstract
Method and apparatus for providing a controlled voltage to an integrated circuit is described. A first frequency value indicative of a first voltage is compared to a second frequency value indicative of a second voltage. The second frequency value is adjusted by the second voltage until the second frequency value is within a range of the first frequency value. Additionally, the second voltage may be adjusted to maintain the second frequency value within the range.
