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 ...

Modern operational amplifiers (op amps) and instrumentation amplifiers (in amps) provide great benefits to the designer, when compared with discrete semiconductors. But all too often, some very basic ...

Originally, operational amplifiers (op amps) were not thought of as candidates for RF design, but the advent of newer, faster devices has now made them an attractive option for some applications. The ...

If you’ve ever wondered why an op amp has the little plus and minus symbols on it, its because at the heart of it, the device is a differential amplifier. The problem is that — ideally, at least — it ...

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 ...

Though sometimes taken for granted, designers shouldn’t overlook the intricacies of voltage- and current-feedback op amps—integral players in the analog and mixed-signal worlds. Op amps amplify tiny ...
