Research Abstract

This project discussed the impedance calculation technique of on-chip power distribution network using ferromagnetic resonance loss generated in magnetic films at GHz frequency range. We evaluated the magnetic circuit model with the leakage magnetic flux path for considering the demagnetizing field generated in the magnetic film. The result shows the ferromagnetic film integrated onto the on-chip power lines can be designed by an electromagnetic field simulator based on the Maxwell's equation at 1-7GHz.
