本論文係說明HDMI傳輸介面所使用之共模拒斥濾波器(Common-mode rejection filter)設計、模擬與量測，並以Murata及TDK的設計技術為藍本，研究及突破HDMI共模拒斥濾波器必要的相關關鍵技術，進而達到技術創新及產品化目標。本篇論文中，首先以變壓器理論切入，探討各種寄生效應對元件所產生的影響，最後改變一般的平面式螺旋線圈結構，降低高頻寄生效應對元件的影響，使共模拒斥的插入損耗頻寬能更寬頻。

In this thesis, we propose the design methodology, simulation, and measurement of HDMI Common-Mode Rejection Filter (CMRF). Based on the Murata or TDK filter specifications, we optimize the key structural and material parameters of HDMI common-mode rejection filter to build up a novel filter model and successfully transfer this technology to Delta electronics Co. MMBU.
