| Abstract: | A new method to determine the small-signal equivalent circuit of PHEMT is proposed.This method consists of determining both extrinsic and intrinsic elements analytically,and optimizing extrinsic elements by converse analyzing,which result in the precision of extrinsic elements and the whole equivalent circuit much improved.This method is fast and accurate,and the program finished in Matlab is repeatable.The equivalent circuit determined by this method fits S -parameters measured very well up to 20GHz. |
