Abstract
A technique that is readily implemented in monolithic integrated circuits reduces or eliminates phase glitches when switching between input reference clock signals. The technique combines a pulsed phase-difference signal and a pulsed phase-difference compensation signal to substantially attenuate a DC component of the phase-difference signal and at least partially attenuate harmonic components of the phase-difference signal. The pulsed phase-difference compensation signal is based on an indicator of a phase difference between the input reference clock signals.
