Abstract
In one embodiment, the present invention includes a method for determining if a frequency control instruction would cause a first capacitor bank to reach a limit and adjusting the first capacitor bank in a first direction using a calibration value and adjusting a second capacitor bank in a second direction if the first capacitor bank would reach the limit. Furthermore, the calibration value may be calculated and stored in accordance with other embodiments. In such manner, small changes in capacitance and correspondingly small changes in frequency may be effected.
