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 effect, this circuit is an amplitude-bounded constant-slope integrator. Figure 1 This op-amp integrator ramps up or down at a preset rate, holding a final value equal to the input-voltage dc level.

1. Analysis begins with a basic differential op-amp circuit with two inputs: a positive one with gain of +5 and a negative one with gain of –5.

The Analog Engineer’s Circuit Cookbook: Op Amps is an example. It compiles more than 25 popular op-amp circuit designs like current sensing, attenuating, and full-wave rectifying into a single e ...
