Abstract
In one embodiment, an impedance matching network includes variable capacitors. A first variable capacitor has a terminal electrically connected to the RF input. A second variable capacitor has a terminal electrically connected to the RF output. At least one of the variable capacitors is an electrically variable capacitor (EVC). The EVC includes a plurality of parallel-coupled capacitors comprising fine capacitors increasing in capacitance and coarse capacitors having a greater capacitance. A capacitor position for the EVC for enabling an impedance match is determined by a processor using software. An impedance match is enabled by directly switching the electronically variable capacitor to the determined capacitor position.
