Hello,
I am trying to design a frequency error detector and corrector for hysteresis comparator in DC-DC converter system. I would like to maintain the hysteresis comparator output running at reference frequency. What I need to compare the output clock signal from hysteresis comparator with a reference clock frequency and modify the ouput clock signal by some voltage controled delay cells. I do not want to use PLL circuit cause it will bring steablity problem. Are there any better solutions using analog circuits to realize this function? Thanks very much.
