Abstract—The work presented in this paper concerns the modeling of an integrated transformer in monolithic technology for high frequencies containingcoils of planar type and magnetic circuit made of several layers of materials. Circular, square and polygonal shapes of the planar coils are the important difference regarding transformer topologies. In this work, we have chosen the stacked octagonal form of coils. We have opted for the Wheeler method and the S-parameters for determining the geometrical and the electrical parameters.The electrical π model presented summarizes perfectly the various parasitic effects generated by stacked layers of different materials constituting the transformer.The electromagnetic simulation, by using COMSOL Multiphysics 4.3 software, illustrates the current density and the distribution of magnetic field lines.
