[Tim] wanted to help out a ECE student struggling with some Op-Amp problems ... What he does is show how this — like most circuit solving problems — depends on how you group the components ...

a very simple op amp circuit with some detail omitted If you open this circuit in the Falstad simulator, you’ll see two sliders to the right where you can tweak the input voltage. If you make ...

Despite the monolithic op amp being older than SPICE simulators, comprehensive op-amp SPICE modeling left a lot to be desired ...

This high-resolution audio amplifier delivers exceptional sound quality with a simple yet efficient circuit design.

You need a TVS diode because many voltage regulators do not have the ability to sink current, nor can they respond fast ...
