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 ...

The design of a standard inverting integrator is simple when bipolar supplies are available, but it's cumbersome with a unipolar supply. To allow adequate headroom for the output, the circuit must be ...

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 ...
