| Zusammenfassung: | In one embodiment, a control loop in an electrical circuit includes a variable feed-forward circuit configured to determine a setting of a variable oscillator that would result in a frequency of a first signal approximating a frequency of a second signal. The setting may be used to control the variable oscillator at a time when a phase error between the first signal and the second signal is negligibly small (e.g., substantially zero), thus allowing for relatively short loop convergence time. |
