摘要
This brief presents a design flow for a supply noise insensitive (SNI) phase-locked loop (PLL). The influence on the PILL jitter of each noise component having high/low bandpass filter characteristics is investigated in the time domain. Acquisition time, tracking range, lock range and jitter are key parameters of a PLL system, and they are evaluated with piecewise linear (PWL) behavioral modeling. Finally, the SNI-PLL circuit having worst-case -45-dB power supply noise rejection based on the behavioral simulation results is implemented.
