Abstract
A phase-locked oscillation circuit, which minimizes phase fluctuation of an output clock signal generated by the phase-locked oscillation circuit, is provided. A wavelet filter performs a wavelet converting operation over phase fluctuations of an input reference signal and output clock signal of a phase-locked oscillator. It separates the phase fluctuation into a periodic fluctuation component and a non-periodic fluctuation component, optimizes a gain of the phase-locked oscillator on the basis of the periodic fluctuation component, and optimizes power supply filters of the phase-locked oscillator on the basis of the non-periodic fluctuation component.
