MODELING AND OPTIMIZATION OF AN INTEGRATED PLANAR INDUCTOR WITH TWO LAYERS OF MAGNETIC MATERIAL

The objective of the work carried out in this document is to develop an electrical model of an inductor with two layers of magnetic material. Simulation and optimization have allowed us to develop a model and in order to validate it, we have realized in the laboratory integrated planar components with two layers of magnetic materials.The different technological steps from copper deposition to the realization of the top layer (in the case of two-layer inductors), through exposure, etching, gilding, lapping, sawing, polishing and bonding have been described (Table 1). These steps required the use of the technological means of the laboratory.From the elements extracted by the optimization program, the admittance parameters Y11 and Y12 were recalculated and compared with those obtained by simulation. We noted a good agreement between the measurement and the simulation.
