Negative feedback and Applications using Operational Amplifier
... One solution may consists of cascading many RC filters, using buffer amplifiers (as indicated in Fig. 12) to avoid loading effects. It turns out, such an approach produces indeed steeper rolloff, but the curved “f3dB knee” in the gain vs frequency response does not disappear. On the other hand, filt ...

Negative feedback
Negative feedback occurs when some function of the output of a system, process, or mechanism is fed back in a manner that tends to reduce the fluctuations in the output, whether caused by changes in the input or by other disturbances.Whereas positive feedback tends to lead to instability via exponential growth, oscillation or chaotic behavior, negative feedback generally promotes stability. Negative feedback tends to promote a settling to equilibrium, and reduces the effects of perturbations. Negative feedback loops in which just the right amount of correction is applied with optimum timing can be very stable, accurate, and responsive.Negative feedback is widely used in mechanical and electronic engineering, but it also occurs naturally within living organisms, and can be seen in many other fields from chemistry and economics to physical systems such as the climate. General negative feedback systems are studied in control systems engineering.
