A new approach for parameter extraction of complex models and an application for SPICE MOSFET level-3 static model

In this work, a new approach is presented for specifying the error term use d in the parameter extraction algorithms. By using the new approach, it is possible to remove the differential operations in the algorithms used for t he extraction of parameters in complex models. Also, we present an iteratio n procedure obtained by using the new approach for the extraction of SPICE level-3 MOST static model parameters KP, V-TH, TETA, V-MAX and R-s (= R-D). As well as the triode region parameters, GAMMA, NFS and KAPPA can be found in the overall procedure. Results of the procedure have been compared with the experimental results. It is obvious from this comparison that the new approach is effective for the determination of level-3 model parameters, as for the determination of parameters of proper models.
