Abstract
Certain aspects of the present disclosure provide methods and apparatus for series voltage regulation in an envelope tracking modulated supply. One example of an envelope tracking modulated supply includes a switched-mode power supply (SMPS), a voltage regulator, and a power amplifier having a supply input coupled to an output of the first voltage regulator. In certain aspects, the first voltage regulator is coupled in series between the power amplifier and two or more outputs the SMPS and is configured to generate a voltage at the output of the first voltage regulator based on an envelope of a signal to be amplified by the first power amplifier.
