Feedback is a ubiquitous feature of all integrated circuit and solid-state amplifiers today.
More general and accurate analytical tools based on advanced concepts in circuits and systems theory are often beyond the reach of undergraduate students and practicing engineers, leaving Spice-like computer simulations as the only resort to obtain.
Many analytical methods to model the Feedback loop use approximations that are only apparent to experts, limiting their use by students and most engineers.
