We concluded part 2 of this series by starting to write node and loop equations for a five-resistor Wheatstone bridge circuit ...

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 ...

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 ...

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 ...
