Abstract
A switch mode power supply converter, a parallel amplifier, and a parallel amplifier output impedance compensation circuit are disclosed. The switch mode power supply converter provides a switching voltage and generates an estimated switching voltage output, which is indicative of the switching voltage. The parallel amplifier generates a power amplifier supply voltage at a power amplifier supply output based on a combination of a Vsignal and a high frequency ripple compensation signal. The parallel amplifier output impedance compensation circuit provides the high frequency ripple compensation signal based on a difference between the Vsignal and the estimated switching voltage output.
