Circuit simulations are great because you can experiment with circuits and make changes with almost no effort. In Circuit VR, we look at circuits using a simulator to do experiments without having … ...

In the last Circuit VR we looked at some basic op amp circuits in a simulator, including the non-inverting amplifier. Sometimes you want an amplifier that inverts the signal. That is a 5V input ...

The circuit, shown at left, works with any rail-to-rail op amp; but it works best if the quiescent current is very small compared with the largest current the op amp can sink and if there is a good ...

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 ...

It compiles more than 25 popular op-amp circuit designs like current sensing, attenuating, and full-wave rectifying into a single e-book. Download the e-book for op-amp circuit ideas that you can ...
