Abstract
A linearization system is provided for a Fractional-N Offset Phase Locked Loop (FN-OPLL) in a frequency or phase modulation system. In general, the linearization system processes a modulation signal to provide a linearized modulation signal to a fractional-N divider in a reference path of the FN-OPLL such that a frequency or phase modulation component at the output of the FN-OPLL is substantially linear with respect to the modulation signal.
