==Feedforward Amplifier Circuit, Audio Amplifier and Audio Playing Device - A simplified explanation of the abstract==


This abstract first appeared for US patent application 20240235493 titled 'Feedforward Amplifier Circuit, Audio Amplifier and Audio Playing Device

The patent application describes a feedforward amplifier circuit, audio amplifier, and audio playing device that utilize a main amplifier circuit, adder circuit, sub-amplifier circuit, and subtractor circuit to correct distortion in the output signal.

* The main amplifier circuit introduces distortion to the input signal and feeds it into the adder and subtractor circuits for feedforward correction.
* The sub-amplifier circuit amplifies a second input signal and acts as the positive input for the subtractor circuit, ensuring signal gain consistency with the main amplifier.
* The subtractor circuit reversely amplifies the distorted signal and performs feedforward correction to eliminate distortion.
* The adder circuit combines the distorted signal from the main amplifier with the corrected signal from the subtractor to output a distortion-free signal.

==Original Abstract Submitted==

provided are feedforward amplifier circuit, audio amplifier and audio playing device, including: a main amplifier circuit, an adder circuit, a sub-amplifier circuit and a subtractor circuit, wherein the main amplifier circuit adds distortion to a first input signal to output a distorted signal, and inputs the distorted signal to the adder circuit and the subtractor circuit for performing feedforward correction; the sub-amplifier circuit amplifies a second input signal and serves as a positive input of the subtractor, so that a signal gain output by the subtractor is equal to a signal gain of the main amplifier; the subtractor circuit, with the distorted signal as a negative input, reversely amplifies the distorted signal and afterwards performs feedforward; and the adder circuit superimposes the distorted signal output by the main amplifier circuit and the reversely amplified distorted signal output by the subtractor, so as to output a distortion-free signal.
