Abstract
Reducing transient response in a phase-locked loop circuit. In one instance, a system including a phase detector; a cycle slip detector; and a charge pump electrically connected to the phase detector is provided. The charge pump includes an adapt mode charge pump configured to bypass the phase detector with the cycle slip detector when a frequency error surpasses a first error threshold and an instantaneous frequency surpasses a desired frequency threshold. The charge pump also includes an adapt mode, programmable trickle current source configured to provide a ramp-up trickle current to the phase-locked loop circuit.
