Abstract
In one embodiment, the present invention provides a system including a varactor and a voltage generator. The varactor includes a set of substantially equal voltage-tunable capacitor cells, each having a capacitive range that varies with a first plurality of operating parameters and each providing a capacitance within the range based on a voltage level of a reference voltage. The voltage generator is configured to provide the reference voltage, wherein the voltage level of the reference voltage corresponds to a desired capacitance within the capacitive range and varies based on a second plurality of operating parameters which are substantially the same as the first plurality of operating parameters, and wherein the voltage level of the reference voltage causes each capacitor cell to provide the desired capacitance.
