Abstract

A duty cycle adjustment system includes a time-to-digital converter to generate a plurality of time-to-digital codes from an input signal, a duty cycle index generator to compute a duty cycle of the input signal based upon the plurality of time-to-digital codes, and assign a duty cycle index based upon the computed duty cycle, an input phase assignment generator to generate a first output and a second output based upon the duty cycle index, a first delay line to delay the first output to generate a third output, and a duty cycle generator to adjust the duty cycle of the input signal based upon the third output and the second output.
