Abstract

The disclosed device includes a reference delay circuit for outputting a reference delay circuit output signal from a voltage regulated supply and a noisy delay circuit for outputting a noisy delay circuit output signal from a noisy or droopy supply. The device also includes a phase comparator circuit that is connected to the reference delay circuit and the noisy delay circuit. The phase comparator circuit outputs a phase difference between the reference delay circuit output signal and the noisy delay circuit output signal. Various other methods, systems, and computer-readable media are also disclosed.
