In the fantasy world of schematic diagrams, wires have no resistance and square waves have infinitely sharp rise times. The real world, of course, is much crueler. There are many things you can use to ...

Back to analog, let us start some Schmitt trigger experiments with jellybean bipolar junction transistors… This post explores the classic emitter-coupled Schmitt Trigger circuit. A Schmitt trigger is ...

In this Design Idea (DI), the classic Schmitt-trigger-based RC oscillator is “hacked” and analyzed using the simulation software QSPICE. You might reasonably ask why one would do this, given that ...

We have already given many posts on Op-Amp circuits. But the list of applications of Op-Amp will be keep on going. The best Op-Amp circuit which is used to convert sine waveform into rectangular ...
