Abstract
Examples of circuits and methods for compensating for power supply induced signal jitter in path elements sensitive to power supply variation. An example includes a signal path coupling an input to an output, the signal path including a delay element having a first delay and a bias-controlled delay element having a second delay. The first delay of the delay element exhibits a first response to changes in power applied thereto and the second delay of the bias-controlled delay element exhibits a second response to changes in the power applied such that the second response compensates at least in part for the first response.
