ABSTRACT:
Embodiments of the present invention provide a method of centering an operating band of a voltage controlled oscillator around a desired operating frequency. In one embodiment, an adjustable feedback divider provides for driving an output signal to the top and bottom of the operating band. An adjustable period divider and counter provide a plurality of count values for use in determining a mid-point of the operating band. A capacitance bank provides for selectively adjusting a capacitance of the voltage controlled oscillator, thereby adjusting the operating band.
