Working principle of audio amplifier. IR company’s ir4302 and ir4312 integrate two PWM controllers and digital audio MOSFETs to form a high performance class D audio amplifier. Its output power is 100wx2 (10% thd + N4 Ω load, with radiator) and 60WX2 channel (10% THD)+ N4 Ω, without radiator), with various protection functions, such as over-current protection …

Audio Amplifier Circuit. The circuit of the audio amplifier consists of a transistor a device to apply the input signals and a speaker at the output. The transistors are connected based on the necessity. The important factors that need to be considered while designing a audio amplifier is gain,noise, frequency response and distortion. Higher the gain higher will be the …
How does an amplifier work? - Explain that Stuff
https://www.explainthatstuff.com/amplifiers.html
Every amplifier takes in some kind of input signal (a certain current and voltage, which, together multiply to give a certain power level) and produces a bigger output signal (which may have a different current, voltage, or power). One very basic classification we can make is between voltage and power amplifiers.

https://www.utmel.com/blog/categories/amplifiers/operational-amplifier-basics-working-principle-and-amplifier-circuit
The power amplifier works on the basic principle of converting the DC power drawn from the power supply into an AC voltage signal delivered to the load. Although the amplification is high the efficiency of the conversion from the DC power supply input to the AC voltage signal output is usually poor.

Amplifier Working Principle. The basic principle involved in the working of these amplifiers is that the applied input signal must be applied at the junction that must be forward biased. The output can be collected across the junction of reverse bias. The accurate measurement of the signal can be obtained through the above way.

https://www.gadgetronicx.com/working-audio-amplifier-ic-lm386/
AUDIO AMPLIFIER IC LM386: LM386 is a 8 pin Power amplifier IC suited for low power applications. It has a wide supply range from 4v to 12v and capable of providing voltage gain from 20 to 200. The output gain is internally set to 20 to reduce the usage of external parts and can be modified using two pins of the IC.

Class D power amplifier principle Class D power amplifier is an amplification mode in which the amplifying element is in the switching working state. When there is no signal input, the amplifier is in the cut-off state and does not consume power. During operation, the transistor is brought into saturation by the input
Working principle of a Common Emitter Amplifier - QS Study
https://qsstudy.com/working-principle-of-a-common-emitter-amplifier/
Working principle For the positive half-cycle of the input signal applied to the emitter-base junction, the junction becomes (onward biased. So, more electrons flow from the emitter through the base to the collector and the collector current increases.
