| Abstract: | The impedance-matrix method is employed to calculate the scattering matrix ofmicrowave GaAs FET. And the GA(genetic algorithm) is used to optimize the small-signal equivalentcircuit parameters. This algorithm has the advantages of converging quickly and high accuracy,which can make every parameter in the model to be extracted accurately. |
