Abstract

Envelope Tracking (ET) and Envelope Elimination and Restoration (EER) are techniques which were designed to increase the efficiency of Radio Frequency Power Amplifiers (RF PA) while maintaining a strong linearity of the system. Both techniques employ a special type of DC/DC converter called Envelope Modulator or Envelope Amplifier which has attracted the interest of Spanish power electronics and communications groups since the end of the last decade. This paper summarizes the designs proposed by the Power Supply Systems Group from the University of Oviedo since 2007.
