Fast and smooth highly nonlinear multidimensional table models for device modeling

A general scheme is presented for the construction of device models for circuit simulators. Two general n-dimensional C ¹ table models have been constructed under this scheme. Each table model can automatically reconstruct the exact DC current behavior of two basic physical device models, namely, the Ebers-Moll bipolar transistor model and the GLASMOST MOSFET model. The evaluation times of the three-dimensional table model implementations are less than those of advanced physical CAD device models. The table models are generally very accurate and have negligible model development time. Both table models have been implemented in the SPICE-like circuit simulator PHILPAC
