Samsung patents AI method to improve power amplifier efficiency

Patent drawing from the official filing.

Samsung describes a method for operating a power amplifier that uses AI to adjust input signals before they are amplified. The system splits the signal into a main carrier and a peaking part, applies specific corrections to each, and then combines the amplified results to create a cleaner output.

Why it mattersThis technique could help electronic devices use less battery power while maintaining signal quality, which is useful for smartphones and other portable gadgets.

In the filing’s own words

Apparatuses and methods for operating a power amplifier are provided. In some embodiments, the method includes receiving a first carrier signal and a first peaking signal, generating a first predistorted carrier signal by applying a first predistortion to the first carrier signal, and generating a first predistorted peaking signal by applying a second predistortion to the first peaking signal. The method further includes providing the first predistorted carrier signal to a first power amplifier and the first predistorted peaking signal to a second power amplifier, generating an amplified carrier signal using the first power amplifier, generating an amplified peaking signal using the second power amplifier, and combining the amplified carrier signal and the amplified peaking signal into an output signal.

What exactly they claim (claim 1)

1. A method for operating a power amplifier, the method comprising: receiving a first carrier signal and a first peaking signal; generating a first predistorted carrier signal by applying a first predistortion to the first carrier signal; generating a first predistorted peaking signal by applying a second predistortion to the first peaking signal; providing the first predistorted carrier signal to a first power amplifier and the first predistorted peaking signal to a second power amplifier; generating an amplified carrier signal using the first power amplifier; generating an amplified peaking signal using the second power amplifier; and combining the amplified carrier signal and the amplified peaking signal into an output signal.
