==Original Abstract Submitted==

A multi-transmission envelope tracking (ET) circuit is provided. The multi-transmission ET circuit includes multiple voltage circuits configured to generate multiple modulated voltages for amplifying multiple radio frequency (RF) signals, respectively. Each of the voltage circuits is configured to generate a respective modulated voltage based on a respective supply voltage so generated to prevent amplitude distortion in the respective modulated voltage. In this regard, a control circuit is provided to determine an appropriate supply voltage for each of the voltage amplifiers. In embodiments disclosed herein, the control circuit determines a respective supply voltage for each of the voltage circuits based on a respective peak-to-peak range of the respective modulated voltage. As a result, it is possible to improve operating efficiency of the voltage circuits concurrent to reducing amplitude distortion, energy waste, and heat dissipation.
