Abstract
Presented herein are techniques for implementing a differential sub-sampling phase locked loop (PLL). A method includes detecting a common-mode voltage on an output of a differential sub-sampling phase detector operating in the differential sub-sampling phase locked loop, and controlling, based on the common-mode voltage, a duty cycle of a feedback signal of the differential sub-sampling phase locked loop that is fed back to the differential sub-sampling phase detector.
