ELECTRONIC DEVICE AND METHOD FOR ENVELOPE TRACKING - A simplified explanation of the abstract
This abstract first appeared for US patent application 18519626 titled 'ELECTRONIC DEVICE AND METHOD FOR ENVELOPE TRACKING
Simplified Explanation
The electronic device described in the patent application includes a processor, a modulator, and a power amplifier. The processor executes a first ET shaping function on a baseband signal, the modulator detects the magnitude of the baseband signal and outputs a first voltage based on this magnitude, and the power amplifier amplifies the signal based on the first voltage. The relationship between the baseband signal and the first voltage is defined as Vpa=a|X|+b, where X is the baseband signal, Vpa is the first voltage, and a and b are constants. A look-up table records the relation curve between the power of the amplified signal and the first voltage when a second ET shaping function is used for envelope tracking.

Original Abstract Submitted
An electronic device includes a processor, a modulator, and a power amplifier. The processor receives a baseband signal and executes a first ET shaping function on the baseband signal. The modulator receives the baseband signal, detects the magnitude of the baseband signal, and outputs the first voltage according to the magnitude of the baseband signal. The power amplifier outputs an amplified signal based on the first voltage. The first ET shaping function enables the relationship between the baseband signal and the first voltage to be Vpa=a|X|+b. X is the baseband signal, Vpa is the first voltage, and a and b are constants. The look-up table records the relation curve between the power of the amplified signal and the first voltage when the second ET shaping function is used for envelope tracking.
