Abstract
A frequency divider includes a prescaler and multiple modulus dividers commonly coupled to the prescaler. The prescaler generates intermediate frequency signals having a same phase difference with respect to one another in response to an oscillation frequency signal. The prescaler operates at a first frequency. The modulus dividers respectively divide the intermediate frequency signals with respective ratio to provide a plurality of division frequency signals in response to a control signal. The modulus dividers operate at a second frequency less than the first frequency.
