Frequency response of feedback amplifiers
... • In real oscillator design, we usually design loop-gain magnitude slightly larger than unity at the desired frequency of oscillation. Because a higher gain magnitude results in oscillations that grow in amplitude with time, eventually, the amplitude is clipped by the amplifier so that a constant-am ...

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.
