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 ...

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 ...

Heuristic derivation of a circuit that does not require an ADC to digitize the integral over time of an input signal. As an applications engineer for a company making configurable analog products, I ...
