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 ...

A current-mode operational amplifier (op amp) is configured quite differently from the garden variety op amps we usually use. That configuration and its algebraic circuit analysis will be covered here ...

In previous articles—Common op-amp circuits, Op amps do integration, and The practical op-amp differentiator is quite versatile—we looked at some classic op amp circuits. These circuits used negative ...

In a simplified schematic from its datasheet, Linear Technology's LTC6268 (and 6269 dual) provide no evidence of "secret sauce." Rather, it shows a combination of semiconductor design and process ...
