Abstract
A computing device is disclosed comprising digital circuitry including a critical path circuit, and a gate speed regulator. A ring oscillator generates an oscillation frequency, and dither circuitry periodically adjusts a number of inverter elements in the ring oscillator in order to adjust an average propagation delay of the ring oscillator relative to a propagation delay of the critical path circuit. A comparator compares the oscillation frequency to a reference frequency to generate an error signal, and an adjustable circuit, responsive to the error signal, adjusts at least one of a supply voltage and a clocking frequency applied to the digital circuitry.
