Abstract
A frequency divider including a first frequency-dividing unit, a second frequency-dividing unit, a selecting unit, and a counting unit is provided. The first frequency-dividing unit receives an input signal and divides a frequency of the input signal for outputting a plurality of phase signals, wherein phases of the phase signals are mutually different. The selecting unit is connected to the first frequency-dividing unit for selecting one of the phase signals according to a control signal, so as to output an inner signal. The second frequency-dividing unit is coupled to the selecting unit for dividing a frequency of the inner signal to serve an output signal. The counting unit is coupled to the selecting unit for counting the inner signal and outputting a counting result as the control signal. Therefore, the output signal with about 50% duty cycle can be provided.
