In my previous article on common op-amp circuits, I mentioned that operational amplifiers were used for analog computing, where analog circuits simulated the behavior of complex systems. That article ...

Op-amp integrators can ramp to saturation, and a capacitor-discharge switch can reset them. Alternatively, you can input-switch them to ramp up and down in triangle-waveform-generator applications.

Bob Pease got an e-mail in 2006 from an engineer who was having trouble with an integrator circuit. Amplifiers are often called op amps because they were originally used as operational amplifiers.

This file type includes high resolution graphics and schematics when applicable. Laboratory data often appears as Gaussian curves, and today's laboratory data-acquisition software is designed to ...
