Optimum Digital Filter for High-Performance All-Digital Phase-Locked Loop
The effect of all-digital phase-locked loop (ADPLL) digital filter parameters on the jitter is investigated in time domain,and a systematic design procedure for ADPLL is presented.The pro posed method not only estimates the output jitter of an ADPLL,but also finds the optimal filter pa rameter minimizing the overall ADPLL timing jitter.To verify the theoretic analysis,an ADPLL behavior model in matlab is designed.The simulation shows significant performance improvement on the timing jitter.
