Abstract
A switch mode power supply converter and a feedback delay compensation circuit are disclosed. The switch mode power supply converter has a switching voltage output and provides a switching voltage at the switching voltage output, such that a target voltage for a power amplifier supply voltage at a power amplifier supply output is based on the switching voltage. Further, the switching voltage is based on an early indication of a change of the target voltage. The feedback delay compensation circuit provides the early indication of the change of the target voltage.
