Abstract
The present invention provides for a solution to reduce locking time with satisfactory performance without the need for significant footprint area for the phase lock loop (PLL) circuits by boosting phase frequency detector (PFD) and charge pump (CP) gains through various circuitry configurations that employ one or more flip-flops, delay elements and advanced circuitry techniques.
