After my last Signal Chain Basics article, The basics of op amp loop-stability analysis: A tale of twin loop-gains, I received questions about how to generate the open-loop SPICE simulation curves ...

Let’s say that for a project you are working on, you need an op amp (of course, I would like it to be one of one of Touchstone’s op amps), and you want to make sure that the amplifier meets your ...

Feedback refers to a core concept in circuit design and control theory, used to stabilize amplifiers and control system behavior. This article outlines the fundamental architecture of feedback, ...

Negative feedback is used in voltage regulators, point-of-load (POL) regulators, voltage references, operational amplifiers (op-amps), and other electronic circuits in order to produce an accurate ...

Though sometimes taken for granted, designers shouldn’t overlook the intricacies of voltage- and current-feedback op amps—integral players in the analog and mixed-signal worlds. Op amps amplify tiny ...
