Abstract
In one embodiment, an impedance matching network includes a variable reactance circuit providing a variable capacitance or inductance. The variable reactance circuit includes reactance components and corresponding switching circuits. Each of the switching circuits includes a diode and a driver circuit to switch the diode. The driver circuit includes first and second switches coupled in series. A first driver is coupled to the first switch, a second driver is coupled to the second switch, and a third driver is coupled to the first and second drivers. The third driver provides a first signal to the first driver, and a second signal to the second driver. In providing the signals, the third driver increases and decreases a duration of a dead time between (a) driving the first driver on and the second driver off, or (b) driving the second driver on and the first driver off.
