Abstract
A method and apparatus for improving the performance of a phase-locked loop are disclosed. A phase error between two signals is sensed and a temporary increase in the bandwidth of the phase-locked loop is provided responsive to the sensed phase error. The phase-locked loop may comprise a charge pump and the temporary increase in the bandwidth of the phase-locked loop may comprise a temporary increase in charge pump current. An increase in phase-locked loop bandwidth is followed by a decrease in the bandwidth responsive to a decrease in phase error. The decrease in bandwidth may comprise a decrease in charge pump current.
