A new software tool to model measured RF-data with optimum circuit topology

In this paper a new S/W tool is presented to model measured RF data employing immitance interpolation techniques. This S/W tool also employs a recently developed sub-routine, which generates circuit models with least number of circuit elements by means of a numerical approach. Furthermore, an analytic procedure is introduced and implemented within the new S/W package to select proper sample-points subject to interpolation error in the "near min-max sense" or the so-called "Chebysev sense". Hence optimum circuit topology for the given data is constructed. An example is presented to exhibit the utilization of the new tool. This new S/W package may be utilized as the front end to the commercially available design and analysis package such as ANSOFT, EAGLEWARE etc.
