The humble op-amp can be configured into so many circuit building blocks that it has become an indispensable tool for designers. It’s tempting to treat an op-amp as a triangular black box in a ...

But an analog computer built with a handful of op amps can model a ball ... an object bouncing around inside the virtual box is the job of two separate circuits, one to determine the Y-coordinate ...

Despite the monolithic op amp being older than SPICE simulators, comprehensive op-amp SPICE modeling left a lot to be desired—until now.
