There are dozens of examples of turdv stupidity.

    "I love it when they try to ridicule us by
    quoting us being absolutely correct."

Yes, negative feedback does keep a circuit stable. This is simply a fact.

Pay no attention to what is actually taught at the top colleges and 
universities in the world. Turdv must believe that if he repeats his 
ignorance enough times that it will magically become correct.

The turdv idiot and his pretend BSEE degree.

Negative Feedback
A major breakthrough was invention of the feedback amplifier in 1927 by 
Harold S. Black. Black used negative feedback which reduces the gain but 
makes the amplifier very insensitive to variations in tube characteristics. 
This invention made it possible to build **stable amplifiers** with linear 
characteristics.


Positive Feedback
In a system with positive feedback, the increase in some variable or signal 
leads to a situation in which that quantify is further through its dynamics. 
This has a **destabilizing** effect and is usually accompanied by a 
saturation that limits the growth of the quantity.

If we introduce positive, or regenerative, feedback into an amplifier 
circuit, it has the tendency of creating and sustaining oscillations.

Negative feedback, on the other hand, has a "dampening" effect on an 
amplifier. While positive feedback drives an amplifier circuit toward a 
point of instability (oscillations), negative feedback drives it the 
opposite direction: toward a point of stability.

OSCILLATORS

We have already talked about FEEDBACK in terms of NEGATIVE FEEDBACK to 
stabilize a circuit. We will now cover a new term called POSITIVE FEEDBACK - 
it changes the performance of circuit completely. It makes the circuit 
OSCILLATE. Negative feedback "kills" a circuits performance - positive 
feedback makes it oscillate.
