On the modeling of electron devices: Concept, accuracy criterion with application examples, importance in EE education

In this work we investigate the accuracy criterion of the electron device models and give practical circuit examples. The analysis and design of integrated circuits depend heavily on the utilization of suitable models for integrated-circuit components. Since any analysis is only as accurate as the model used, it is essential that the circuit designer have a thorough understanding of the origin of the models commonly utilized and the degree of approximation involved in each. The subject investigated demonstrates clearly the importance of the modelling in EE education.
