Abstract
An envelope tracking device includes circuitry that senses a current of an input state of the envelope tracking device. The circuitry also senses an output voltage of the envelope tracking device, and turns on at least one of a first and a second output switches to generate an output current based on at least one of the sensed current and the sensed voltage.
