A phase-locked method includes: generating a selection signal according to a detection result of a phase/frequency detector (PFD) of a phase-locked loop (PLL); generating a plurality of oscillation signals according to at least a first oscillation signal generated by the PLL, wherein the plurality of oscillation signals respectively correspond to a plurality of phases; and from the plurality of oscillation signals, selecting an oscillation signal as an output signal of the PLL according to the selection signal.
