Abstract
A fast lock scheme for phase locked loops and delay locked loops, where apparatus, systems, and methods include a startup circuit that is enabled at the beginning of a startup mode and is disabled upon a phase transition detection in the reference and feedback signals to the phase locked loop or delay locked loop. Further apparatus, systems, and methods enable a first charge pump when a phase transition is detected, and enable a second charge pump when the phase difference between the reference and feedback signals fall within a predetermined range.
