Abstract
A system for dynamically trimming a voltage controlled oscillator operable to receive a trim signal for adjusting a voltage-to-frequency operating characteristic of the voltage controlled oscillator and receive a tune signal to generate an output signal having an output frequency determined by the voltage-to-frequency operating characteristic includes a trim circuit operable to receive the tune signal and generate the trim signal and increment or decrement the trim signal and condition a change in the trim signal during the increment or decrement so that the voltage-to-frequency operating characteristic of the voltage controlled oscillator drifts from a first voltage-to-frequency operating characteristic to a second voltage-to-frequency operating characteristic.
