An on-Chip Transformer in Ferrite-Based Technology

This paper present a characterization of an integrated transformer, stacked and intertwined. It is decomposed into three parts. First of one concern a presentation of a monolithic transformer topologies. Then the geometric dimensions and elec-trical model of our component are presented. An equivalent model is proposed to calculate a quality factor. The last part concerns thermal simulation using the software Comsol 5.3 that allowed us to determine the operating temperature in the materials of this integrated planar transformer, stacked and intertwined without magnetic core and with magnetic core in 3D space dimension.
