  • Methods and arrangements to adjust a duty cycle
    Patent number: 7298193
    Abstract: Embodiments may include a duty cycle controller to adjust the duty cycle of the clock signal based upon a delay signal and an input clock signal. A duty cycle detector may determine signals with frequencies based upon the duty cycle of the output signal and a correction module may compare the frequencies of the detector signals to generate the delay signal. In some embodiments, once the duty cycle of the output clock signal reaches the desired duty cycle such as fifty percent, the correction module may be turned off.
