Popis: An all-digital measurement circuit, built in 45-nm SOI-CMOS, enables on-chip characterization of phase-locked loop (PLL) response to a self-induced phase step. This technique allows estimation of PLL closed-loop bandwidth and jitter peaking. The circuit can be used to plot step-response vs. time, measure static phase error, and observe phase-lock status.
