Abstract
An envelope tracking arrangement is disclosed and includes a level select component, a chunk supply component and a power amplifier. The level select component is configured to segment an input signal into chunks based on time and to select a chunk level for each chunk based on information or envelope information. The chunk supply component is configured to selectively provide a discrete supply voltage according to the selected chunk level. The power amplifier is configured to generate a radio frequency (RF) output signal based on the input signal and utilizing the discrete supply voltage.
