Stable Parametric Macromodeling Using a Recursive Implementation of the Vector Fitting Algorithm |
| |
Abstract: | A novel least-squares fitting technique is presented for the macromodeling of parameterized frequency responses. Such parametric macromodel can be used for the design, study, and optimization of microwave structures. A key benefit of the proposed method, is that the poles of the macromodel are guaranteed stable by construction. This can easily be enforced when using the presented macromodel representation. |
