An apparatus for detecting a phase of an input signal includes: a phase detector unit for detecting the phase of the input signal referring to a plurality of clock signals having different phases and for outputting a plurality of phase detection results, wherein each of the phase detection results represents a candidate phase of the input signal and corresponds to one of the clock signals; and a phase decision unit, coupled to the phase detector unit, for determining the phase of the input signal according to the phase detection results.
