Controllable oscillator with output oscillation adjustment and method for producing an output oscillation for use therewith

摘要

A controllable oscillator includes an output oscillation adjust module operably coupled to an oscillator for producing an effective output oscillation based on an oscillation control signal. The output oscillation adjust module includes an output select block that produces the effective output oscillation from a sequence of selected taps from the plurality of taps of the oscillator. A tap adjust control generator, responsive to the oscillation control signal generates a sequence of tap adjust control signals that command the output select block to select the sequence of selected taps from the plurality of taps. The tap adjust control generator includes an integrator having an integrator output, responsive to the oscillation control signal and a modulo(x) module for producing the sequence of tap adjust control signals based on the integrator output.
