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 ...

Here is another tip of the hat tip of the soldering iron to one of the Planet Analog archived posts. This post gives an explanation of how op-amps work in general and how an integrator works in ...

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 ...
