A negative feedback amplifier (or feedback amplifier) is an electronic amplifier that subtracts a fraction of its output from its input, so that negative feedback opposes the original signal.

Due to negative feedback, input signal - feedback signal (so appose it).

In phase shift 180 degree oscillate, regeneration process the negative feedback opposes the input signal.

In negative feedback we apply output to the input by phase reversing so it opposes the input signal.

In positive feedback some amount of input signal form regeneration process so negative feedback opposes the input signal.
