Abstract
A system for controlling an output frequency of a dual-input voltage controlled oscillator relative to a reference frequency is provided. The method includes the step of coupling a first tune control signal to a first input of the dual-input voltage controlled oscillator. The method further includes the steps of dividing the output frequency of the dual-input voltage controlled oscillator by a value substantially equal to a second tune control signal, comparing a phase of the divided output frequency with a phase of the reference frequency and coupling a phase difference of the compared phases to a second input of the dual-input voltage controlled oscillator.
