Abstract
Years before microcontrollers and digital computers were introduced, control system operations, industrial computations, and even simulation of dynamical systems were made possible by use of analog computers. The heart of an industrial analog computer is a device called operational amplifier or “opamp.” These amplifiers consist many transistors to accomplish a theoretical infinite gain to either inputs.
