A regulator is a closed-loop feedback system. For the LDO to be stable, the phase margin must be positive. In other words, at unity gain crossover frequency of the gain curve, the phase of the system ...

This article presents loop stability analysis in analog and digital feedback systems. It presents finding the analog loop stability experimentally and by using Laplace transform, as well as finding ...

Download this article in .PDF format This file type includes high resolution graphics and schematics. Feedback systems have a wide range of applications including different types of amplifiers, signal ...

These three analysis methods are linked together, so this section is organized by control method. In contrast to the large-signal transient response that was reviewed in part 2, we will perform ac ...
