Abstract
A self-tuning variable impedance circuit provides improved performance. A variation in the power applied to the variable impedance circuit causes a corresponding change in the impedance of the circuit, resulting in improved performance. For example, the variable impedance circuit may be a matching circuit that 'follows' the output power of a power amplifier, thereby increasing the power efficiency of the power amplifier.
