The operational amplifier is arguably the most useful single device in analog electronic circuitry. When you apply them in the circuits, you must know their basics and functions. As for the function ...

Operational amplifiers (op amps) have proliferated from specialized instruments made from large tubes to tiny monolithic circuits composed of a sliver of silicon, germanium or gallium arsenide. Dozens ...

Op amps are the basic building blocks for much of linear circuit design. You probably learned about them in college and even designed some products containing an op amp. As an electronic engineer, you ...

You think of op amps as amplifiers because, no kidding, it is right in the name. But just like some people say, “you could do that with a 555,” [Doctor Volt] might say, “you can do that with an op amp ...

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 ...

Part 5 provides spec summary of the GP/R K2-W vacuum-tube op amp and discusses measurement constraints/conditions and LTspice modeled output. The K2-W vacuum-tube op ...
