Abstract
A phase lock loop pre-charging system and method are described. In one embodiment, a phase lock loop pre-charge system includes a bias component for generating a pre-charge voltage, and an activation component for activating the bias component. In one exemplary implementation the pre-charge voltage is utilized to facilitate pre-charging of a phase lock loop voltage controlled oscillator. In one embodiment, the bias component includes replica bias components that track the voltage controlled oscillation control voltage over varying process, voltage and temperature characteristics. The phase lock loop pre-charging systems and methods can be utilized to reduce lock time for a circuit.
