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 ...

I ran into a seemingly odd result the other day in a simulation I was running on Multisim 12 using the three terminal virtual op-amp. This sketch shows what I found: Clearly, something was amiss. A ...

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 ...

A comparator is a great circuit because it provides a near ideal transition between the analog and digital domains. The comparator looks at two linear input signals and gives a digital output that’s ...
