Title: Decision method for parameter of fet equivalent-circuit model
Inventor: TSAI ROGER SU-TSUNG
IPC: G06F17/50
Filed: 2001-02-23
Abstract: PROBLEM TO BE SOLVED: To unequivocally extract an intrinsic component and a parasitic component. SOLUTION: When an FET equivalent-circuit model is developed, the set of S-parameter values which are related to an FET device is measured in order to generate the set of parameters of an equivalent circuit, and the circuit model is generated (102 to 108). A trial impedance point Rs is prescribed (110) with reference to the circuit model. For the point, a model S-parameter value is extracted (112), On the basis of the extracted model S-parameter value, a modeling S-parameter is calculated (114) so as to be compared with a measurement S-parameter (118). For the trial impedance point, the modeling S-parameter value is optimized (122). The error degree between the optimizing S-parameter value and the measurement S-parameter value is calculated (124). The trial impedance point in which the error degree is minimum and a model parameter point are selected (126).  Thereby, the set of the parameters of the equivalent circuit regarding the FET device is decided.
