Original Abstract Submitted
A phase interpolator includes a sampling circuit configured to capture samples of an output of the phase interpolator, a delay circuit configured to delay sampling by the sampling circuit, a comparator configured to provide a comparison signal that indicates whether voltage of the samples exceed a reference voltage, and a counter responsive to the comparison signal and configured to provide an output that controls an operating point of the phase interpolator. The phase interpolator my further include a pair of driver circuits configured to concurrently drive the output of the phase interpolator.
