Patent ID: 7486148

Claim:
A phase locked loop comprising: a difference detection module operably coupled to determine a difference signal based on at least one of a phase difference and a frequency difference between a reference oscillation and a feedback oscillation; a loop filter module operably coupled to convert the difference signal into a control signal; an oscillator having a plurality of taps for producing a plurality of outputs, the oscillator operably coupled to convert the control signal into an output oscillation; an output oscillation adjust module operably coupled to the oscillator for producing an effective output oscillation based on an oscillation control signal, wherein the output oscillation adjust module includes: an output select block, operably coupled to the plurality of taps, for producing the effective output oscillation from a sequence of selected taps from the plurality of taps based on a sequence of tap adjust control signals; and a tap adjust control generator, responsive to the oscillation control signal that includes an integrator having an integrator output, responsive to the oscillation control signal and a modulo(x) module that produces the sequence of tap adjust control signals based on the integrator output; and a divider module operably coupled to convert the effective output oscillation into the feedback oscillation.
