Abstract
An adjustable duty cycle clock generator has first and second delay lines coupled to receive an input clock and cascaded to first and second edge detectors, respectively. The second delay line has a programmable delay and the first and second edge detectors are further coupled to set and reset inputs on an S-R latch to generate an adjustable duty cycle clock with independently adjustable high and low times proportional to the induced delays of the first and second delay lines.
