Fractional-Enphase Synchronous Loop with Self-correcting Fractional Delay Element

摘要

The delay interval for the feedback signal is increased if a small fractional divisor (1/2) resulting in a lagging phase relationship or a large fractional divisor ( 1/2) resulting in a leading phase relationship is detected. Become; Self-correcting fractional delay element that controls the PLL feedback signal in a reduced manner when a small fraction divisor (1/2) resulting in a fast relationship or a large fraction divisor ( 1/2) resulting in a ground relationship is detected. A fractional-N phase locked loop (PLL) with a delay lineloop (DLL).
