Abstract
Computer simulation of electric and electronic circuits has become an important analytical tool for circuit design. Several fine programs are available, but none of them provide a model for an operational amplifier. Since operational amplifiers are such basic building blocks for analog electronics, many researchers have developed macromodels to fill this void. Their models, however, tend to be very general and difficult to use, especially for the unexperienced designer who wishes to simulate his circuit. This thesis presents a systematic macromodeling procedure for operational amplifiers. The procedure is used to develop minimal component macromodels tailored to a specific device and application. By eliminating extraneous device parameters, the designer develops straightforward macromodels which are nonetheless accurate. The procedure has been tested for several kinds of circuits, comparing theoretical and experimental results to those from computer simulation. The macromodels developed in this manner are thus shown to correspond very well with theoretical expectations and experimental observations.
