Negative Feedback Amplifier

A negative feedback amplifier is a type of electronic device that stabilizes and improves its own performance. It works by taking a small portion of its output signal, reversing its phase (making it negative), and feeding it back into the input. This process reduces distortions, controls gain, and enhances accuracy. Essentially, negative feedback helps the amplifier work more reliably, with less noise and distortion, making it useful in audio equipment, radios, and various electronic systems where precise amplification is needed.
