Abstract
In one embodiment, the present disclosure is directed to a method for matching an impedance. The method can include determining or receiving a reflection parameter value at an RF input or output; stopping the altering of a first capacitance and a second capacitance when the reflection parameter value is at or below a first reflection value; causing a limited altering of the first capacitance and the second capacitance to pursue an impedance match when the reflection parameter value is at or above a second reflection value and at or below the third reflection value; and causing an unlimited altering of the first capacitance and the second capacitance to pursue an impedance match when the reflection parameter value is at or above a third reflection value.
