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 ...

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 ...

In this chapter you will encounter some applications of positive feedback in op amp and comparator circuits. You will see how uncontrolled feedback can cause unwanted oscillation, and how controlled ...

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 ...

My caller last week was in a real bind. The design was almost done and he had run out of room. He needed help. The system needed a comparator function and the circuit board was full. After going over ...

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 to ...
