Abstract :
This paper introduces a technique for suppressing the effect of deterministic jitter in phase-locked loops based on multiplying delay-locked loops. A digital loop operating in background of normal operation detects the static phase offset between the two reference-signal paths by means of a single-bit time-to-digital converter and compensates for it by means of a digital-to-time converter.
