If a specific transistor can not be found in the component library of Mulitisim simulation software, a new transis-tor model need to be established and its parameters should be determined. The physical meaning of the transistor G-P model pa-rameters is elaborated in this paper in 7 aspects, such as current characteristics, output characteristics, etc. Furthermore, the esti-mation method of transistor model parameters is illustrated by an instance in normal situation. The accuracy of the model parame-ters was verified in the experiment. The experiment results indicate that the proposed method is of good simulation performance and practicality.
