Untuk sistem isyarat pembezaan berbilang saluran sebenar, keseimbangan ideal atau topologi simetri tidak dapat diwujudkan, dan oleh itu, komponen ketidakseimbangan teruja. Walau bagaimanapun, kaedah analisis teori untuk menilai taburan voltan dan arus pada talian berpasangan pembezaan, yang membolehkan untuk menjangka sinaran EM pada peringkat reka bentuk dan mengkaji cara yang mungkin untuk menindas komponen ketidakseimbangan, belum dilaksanakan. Untuk memberikan pertimbangan asas bagi sinaran elektromagnet (EM) daripada struktur talian berpasangan pembezaan asimetri praktikal dengan penghalaan sama panjang yang digunakan dalam reka bentuk papan berkelajuan tinggi, kertas ini baru mencadangkan kaedah analisis untuk menilai voltan dan arus pada sebarang titik pada pembezaan. -garisan berpasangan dengan menyatakan garis berpasangan pembezaan dengan litar sumber setara dan litar beban setara. Kaedah yang dicadangkan boleh meramal S-parameter, taburan voltan dan arus dan sinaran EM dengan ketepatan yang mencukupi. Selain itu, kaedah yang dicadangkan menyediakan fleksibiliti yang mencukupi untuk parameter geometri yang berbeza dan boleh digunakan untuk membangunkan pandangan fizikal dan garis panduan reka bentuk. Kajian ini telah berjaya mewujudkan kaedah asas untuk meramalkan integriti isyarat dan isu gangguan EM secara berkesan pada talian berpasangan pembezaan.

Abstract: For actual multi-channel differential signaling system, the ideal balance or symmetrical topology cannot be established, and hence, an imbalance component is excited. However a theoretical analysis method of evaluating the voltage and current distribution on the differential-paired lines, which allows to anticipate EM radiation at the design stage and to study possible means for suppressing imbalance components, has not been implemented. To provide the basic considerations for electromagnetic (EM) radiation from practical asymmetrical differential-paired lines structure with equi-length routing used in high-speed board design, this paper newly proposes an analytical method for evaluating the voltage and current at any point on differential-paired lines by expressing the differential paired-lines with an equivalent source circuit and an equivalent load circuit. The proposed method can predict S-parameters, distributions of voltage and current and EM radiation with sufficient accuracy. In addition, the proposed method provides enough flexibility for different geometric parameters and can be used to develop physical insights and design guidelines. This study has successfully established a basic method to effectively predict signal integrity and EM interference issues on a differential-paired lines.
