Abstract:Modern Spice-like circuit simulators use increasingly accurate and sophisticated analytical models of components. But the validity of models, that is the probability that the procedure of the model verification is true, still remains very poor. The reason is that the mathematical models cannot be created without some simplifying assumptions. To solve this problem we suggest the use of real transistors instead of their mathematical models. It is shown that semi-natural models built on the basic of real transistors allow to control the transistor length and width with an error of a fraction of percent. Besides, they have an admissible speed and can be embedded into Spice-like simulators. The preferred way of the model use is a forecast of the radiation and temperature infuence on the circuit to be designed and solution of some simulation problems that require high validity and accuracy.
