ABSTRACT:
A switching voltage regulator is disclosed for regulating a voltage supplied to system circuitry. The switching voltage regulator comprises an oscillator operable to generate an oscillator signal representing a gate speed of a reference circuit in the system circuitry, and a frequency generator operable to generate a reference signal representing a target gate speed of the reference circuit. A cycle comparator compares at least one cycle of the oscillator signal to at least one cycle of the reference signal, and switching circuitry charges a charging element based at least on part on the comparison.
