Stabilization of feedback amplifiers

A MPLIFIERS and other dynamic systems can be classified as stable or unstable depending on the nature of their transient response. The stabilization problem for a feedback amplifier arises in the first place because of the presence of one or more of the roots of the characteristic equation in the right half of the complex frequency plane. It is useful, therefore, to consider the solution of the stabilization problem directly in terms of the transient response, rather than in terms of frequency response data such as gain and phase margins.
