Abstract

We used a simple method based on fast magnetostatic computations in order to analyze proximity effects in integrated inductors with high-permeability magnetic material. This method was applied to spiral micro-inductors and showed good agreement with experiment. These results enlighten the importance of the proximity effect contribution on the total losses of integrated magnetic devices and demonstrated the interest of this simple method for quality factor optimization
