Fractional-en phase locked loop with delay line 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 Fractional-N Phase Locked Loop (PLL) with a delay line loop (DLL).
