Abstract:
A phase-locked loop includes a phase/frequency detector for generating phase error signal according to a reference signal and an input signal, a charge pump for outputting a voltage signal according to the phase error signal, a voltage-controlled oscillator for outputting an output signal corresponding to the phase error signal according to the voltage signal, an adaptive adjusting unit for outputting a control signal according to the phase error signal, so as to form a nonlinear between the output signal and the phase error signal.
