PROPORTIONAL PHASE COMPARATOR AND METHOD FOR PHASE-ALIGNING DIGITAL SIGNALS

摘要

Embodiments of a proportional phase comparator and method for aligning digital signals are generally described herein. In some embodiments, circuitry to align digital signals comprises a proportional phase comparator that generates triangular-shaped pulses for application to a charge pump. The triangular-shaped pulses may reduce an amount of charge injection in the charge pump close to convergence.
