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 ...

(Editor's Note: There are links to the previous parts of this series at the end, below the author's biography.) In the first article of this series, “Operational Amplifier–The Basic Building Block” ...

As an applications engineer for a company making configurable analog products, I occasionally get asked to provide a design to integrate a signal before digitizing it. In many cases, the people doing ...

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.
