Abstract :
An exact method for designing loop filters in third-order PLLs is presented. The method is simple and results in a PLL with superior loop dynamics and improved output jitter while maintaining the same loop bandwidth compared to that of a PLL designed using the conventional approach. The method is readily applicable to higher order PLLs
