Abstract

Various embodiments of the present invention relate to a power amplification device and method, wherein the power amplification device can comprise: a power amplifier; a switch mode converter for controlling a bias of the power amplifier; a comparator for providing a switching signal to the switch mode converter according to an envelope signal; and a control unit for determining whether a switching frequency of the switch mode converter is within a specific band and applying an offset to the switching frequency so as to deviate from the specific band if the switching frequency of the switch mode converter is within the specific band. Various other embodiments can be carried out.
