Summary form only given. We would like to thank the discussers for their clarification and appreciate their elegant derivation. We already discovered that we were incorrect in claiming the half-size test matrix to be applicable to unsymmetrical models. The error was clarified in a subsequent paper. We would like to mention that we have also derived a half-size test matrix for scattering parameter-based...
The paper introduces an approach for rational macromodeling based on magnitude frequency data. This is achieved by fitting the magnitude square function using vector fitting (VF) with symmetrical basis functions. The procedure is demonstrated to be more robust than a direct application of VF to the magnitude square function.
This paper introduces a new approach for rational macromodeling of multiport devices that ensures high accuracy with arbitrary terminal conditions. This is achieved by reformulating the vector fitting technique to focus on eigenpairs rather than matrix elements. By choosing the least squares weighting equal to the inverse of the eigenvalue magnitude is achieved that the eigenvalues are fitted with...
