A Technique for Semiconductor Devices Modeling Using Physical Templates

A technique of template models creation for semiconductor devices (diodes and field-effect transistors) is developed in this paper. This technique is necessary for solving the problems of analog electronic circuits computer-aided design in robotic systems and space instrument engineering. The template model creation is carried out by the replacement of one or more parameters of the known physical model (template) by the relations of power series of control currents or voltages. The parametric identification of the template model is carried out by the method of least squares. The template model comprises all physical parameters of the initial model. The number of additional parameters in the template model is small (no more than four), which makes it possible to use standard minimum search algorithms for parametric identification. The obtained results show that the proposed template models provide the increase of the accuracy of modeling I-V characteristics of semiconductor devices more than twice in comparison with the known physical models.
