There is an occasional caution that even unity-gain stable Voltage Feedback Amplifiers (VFAs) risk instability in inverting attenuator applications (Reference 1). In fact, there should be no more ...

The very basics of operational amplifiers. Learn comparator, inverting, and non-inverting op-amp configurations. An operational amplifier, or op amp, is a dc-coupled high-gain electronic voltage ...

We took a look at op amp integrators in the previous article, Op amps do integration, so it makes sense to round out the picture by covering differentiator circuits. Of course, differentiation is the ...

Using the circuits below you can study op amps and characterize their behavior. Comparator Inverting Amplifier The comparator demonstrates the ``open-loop'' behavior of an op amp. You can design the ...

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 comparator demonstrates the ``open-loop'' behavior of an op amp. You can design the reference voltage so that the output voltage will ``switch'' whenever the input voltage (at the inverting input ...
