A frequency divider includes a phase selection circuit, control circuit and a retiming circuit. The phase selection circuit is arranged to receive a plurality of input signals with different phases, and generate an output signal by selectively outputting one of the input signals according to a plurality of retimed signals. The control circuit is arranged to receive the output signal to generate a plurality of control signals. The retiming circuit is arranged to retime the control signals to generate the retimed signals according to the input signals
