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 ...
Power supplies use control-loop circuits to produce constant voltage or current. The transfer function—gain and phase as a function of frequency—provides valuable information about a control loop’s ...
To understand a series circuit, visualize it. You can do that by making a drawing. Just draw a box, to start with. This box represents your circuit. Notice there is only one path: the perimeter of the ...
