Impedance Control Technique of On-Chip Power Distribution NetworkUsing Magnetic Film

本计画探讨利用GHz频率范围内磁性薄膜所产生的铁磁共振损耗来计算晶片上电源分配网路的阻抗技术。我们评估的磁路模型与漏磁通路径考虑在磁性薄膜中产生的退磁场。结果表明，基于麦克斯韦方程的电磁场模拟器可以在1- 7 GHz的频率范围内设计出集成在片上电源线上的铁磁薄膜。

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.
