The method of the proposed design is utilized by using defected ground structure (DGS) resonators with the mutual coupling effect between DGS resonators to achieve the broadband common-mode suppression. The proposed structure is etched the DGS resonators on ground plane below the differential signal pair which no additional circuit cost is needed by using the proposed design. For observing in the frequency domain analysis, the differential-mode insertion loss are all above -3 dB from DC to 10 GHz. For the common-mode insertion loss, a wide common-mode suppression bandwidth ( > 6 GHz) is achieved by using -15 dB definition. The equivalent circuit model of the proposed DGS resonators has also been constructed to predict the phenomenon of the common mode suppression. Finally, the result shows a good agreement between simulation and measurement. The results indicate that the proposed common-mode filter has broadband operation on common-mode suppression. In addition, it can maintaining the good signal integrity of differential signal pair. 林丁丙 2013 學位論文 ; thesis 74 zh-TW |
