Abstract
A duty cycle adjustment apparatus includes a duty cycle adjustment determination module configured to determine an adjustment to a duty cycle of a clock signal, and includes a clock delay module configured to receive the clock signal, to delay the clock signal through first and second delay stage modules (with a first and a second plurality of delay paths, respectively) based on the duty cycle adjustment determined by the duty cycle adjustment determination module, and to output the delayed clock signal. The second plurality of delay paths have a greater delay difference between each of the corresponding delay paths than the first plurality of delay paths. The apparatus further includes a duty cycle adjustment module configured to receive the clock signal and the delayed clock signal, to adjust the duty cycle of the clock signal based on the delayed clock signal, and to output a duty cycle adjusted clock signal.
