Abstract
One embodiment relates to a power amplifier that includes a switched mode power amplification stage. The power amplification stage has an output configured to provide an amplified output voltage as a function of a drive signal, where the drive signal fluctuates during a first time and is inactive during a second time. The power amplifier also includes impedance compensation circuitry coupled to the output of the power amplification stage. The impedance compensation circuitry can selectively alter an output impedance of the power amplification stage as a function of a control signal that is continuously de-asserted during the first time and continuously asserted during the second time. Other embodiments are also disclosed.
