摘要：
A novel piecewise model for pHEMTs with accurate I-ds and its first three derivatives (g(m), g(m2) and g(m3)) is presented. The entire operating region is divided into several subregions. Aiming at improving the model accuracy in each subregion, the conventional Angelov models are developed with different optimized parameters. To solve the problem of the discontinuity between adjacent subregions, the artificial neural network (ANN) technique is utilized. The validity of the proposed model is demonstrated by the comparison of measured and modeled results for a pHEMT.
