This paper presents a gray-box modeling technique for obtaining stable and passive circuit models of electrical components. Starting from frequency response measurements and from an initial basic equivalent circuit model, a fully automated procedure performs series and parallel augmentations, the value of the added components being estimated by minimizing the deviation of the model response from measurements. An iterative application of this procedure yields accurate fits, allowing a compact representation of parasitic and second-order effects through suitably and automatically connected circuit elements.
