Abstract
A power amplification system is provided herein. In certain embodiments, the power amplification system comprises: a power amplifier configured to amplify an input radio frequency (RF) signal to generate an output RF signal when powered by a supply voltage and biased by a biasing signal; an envelope tracker configured to generate an envelope signal that changes in relation to an envelope of the input RF signal; a mode controller configured to set an envelope tracking (ET) mode of the power amplification system based on a modulation bandwidth of the input RF signal; a supply voltage controller configured to control the supply voltage based on the envelope signal when the ET mode is set to a first mode; and a bias controller configured to control the biasing signal based on the envelope signal when the operation mode is set to a second mode.
