Op-amps were an invaluable basic technology in 1969. What today’s op-amps can accomplish has expanded dramatically. At present an op-amp is defined as a general-purpose, DC-coupled, high-gain, ...

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 … ...

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 ...

Op amps are voltage-amplifying devices designed to be used with external feedback components—resistors and capacitors—that are situated between their output and input terminals.
