Abstract
An improved programmable duty cycle generator and method of operation. In one aspect, the generated output signal duty cycle is not measured, but rather is generated based on a predetermined value. Saw tooth generator/Integrator schemes are used to create the saw type waveforms of the incoming frequency which in conjunction with DAC is used to create the desired duty cycle. The improved programmable duty cycle signal generator for placement in key pinch points of a critical path where precise duty cycle definition is needed.
