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” ...

In a balanced op-amp circuit, the op-amp inputs see equal impedances looking into the circuit. Balanced circuits provide better performance by cancelling some input errors and have a simple R F /R I ...

Members can download the PDF ebook. One day, back about 1966, I was going up the elevator at 285 Columbus Avenue in Boston to look at some production problems on Philbrick’s fifth floor. And who was ...
