Abstract
In one embodiment, an impedance matching network is disclosed that includes a first circuit comprising a first variable component providing a first variable capacitance or inductance, and a second circuit comprising a second variable component providing a second variable capacitance or inductance. Each of the first circuit and the second circuit includes plurality of switching circuits configured to provide the first variable capacitance or inductance and the second variable capacitance or inductance. Each of the plurality of switching circuits includes a diode and a driver circuit configured to switch the diode. The driver circuit includes a first switch, a second switch coupled in series with the first switch, and a filter circuit that is coupled at a first end between the first switch and the second switch, and is operably coupled at a second end to the diode.
