The development of a SPICE2 model for transient simulation of the Schottky Transistor

Abstract

In order to simulate the Schottky Transistor and its effect on circuit applications, a computer model has been developed for the device. The focus of this research is the development of such a model for SPICE2 (a circuit simulation computer program) using a new method for model construction.

This new method developes a model by approximating the mathematics of the simulation via perturbations and iterations. The model developed by the new method yields a minimum simulation accuracy of 65% in a variety of circuit applications. In comparison, a model developed by the conventional method, which uses measured data to complete the physical constructs of the SPICE2 model, offers the same margin of accuracy for the same circuits. So the new method is just as effective as the old method for the circuits that were tested.

Yet with further development, the new method for model construction can be automated eliminating the time consuming and possibly inaccurate measurements of the old method that would discourage the use of SPICE2. So this research, in addition to developing two successful SPICE2 models for the Schottky Transistor, also introduces a new method for model construction that can make SPICE2 easier to use.
