Table models for device modelling

The author describes a general approach to the automatic construction of C¹ multidimensional (multivariate) device models from table values. By using suitable heuristics, a compact and accurate C¹ table model for highly nonlinear multidimensional behavior can be obtained. As an example, the author generates a table with data from a simple physical MOST model, and compares the results of the interpolation scheme considered with the original physical model. The drain-to-source current behavior of the two-dimensional C² physical model GLASMOST is used as the reference model
