Abstract
A power amplifier of an envelope tracking system is configured to generate an output power with a variable supply voltage that is generated in an envelope tracking path. A signal generation/processing path receives an input signal and processes the input signal to the power amplifier in a main signal processing path. A delay component is configured to generate a delay to the envelope tracking path with respect to the signal generation path. A feedback path is configured to generate a feedback signal from the output of the power amplifier and adjust the delay component or the delay of the delay component during an active transmission or an active transmission mode.
