Did you ever wonder how to calculate the stability of an op amp circuit? Put the wrong compensation network into the feedback loop, and you’re got an attenuator or, worse, an oscillator. It’s not ...

In a previous Idea for Design, Anshi Chen outlined a method for analyzing electrical circuits using Kirchhoff’s current law (KCL) in a novel way that allowed designers to simply write down the needed ...

Author’s note: This article shows how to derive circuit gain equations via a signal flow graph. With practice you may be able to write a gain equation by locating signal paths and loops in the ...

Control systems are all around us, and understanding them is going to make you much better at hardware design. In the last article — Beyond Control: The Basics of Control Systems — we looked at an ...
