## Abstract This letter presents a new technique to enhance the overall efficiency of a two‐stage envelope tracking (ET) power amplifier (PA). Because of heavy gain compression, ET amplifiers can suffer from inefficient driver stages. By reducing the supply voltage of the driver amplifier, its effi
