Abstract
In accordance with an embodiment of the present disclosure a phase-locked loop comprises a voltage controlled oscillator (VCO) configured to generate an output signal based on an input reference signal. The phase-locked loop further comprises a first charge pump communicatively coupled to a control input of the VCO and configured to generate, for a duration of time following occurrence of an event, a first control signal. The first control signal is independent of the output signal and is for causing the output signal to have a first frequency based on a second frequency of the input reference signal. The phase-locked loop further comprises a second charge pump communicatively coupled to the control input of the VCO. The second charge pump is configured to generate, after the duration of time, a second control signal. The second control signal is adjusted to lock the output signal with the input reference signal according to a phase difference between the output signal and the input reference signal such that the output signal is synchronized with the input reference signal.
