The interface of high-speed differential transmission is now indispensable in most high-performance system. Comparing with the traditionally single-ended and parallel transmission, the differential and serial signaling has been proven to have much better performance. Through the transmission of differential signals between adjacent chips, multi-function chips can be integrated into the electronic products to provide better hardware specification and performance. In a highly integrated and high performance system, the design of signal integrity and electromagnetic compatibility has been a very important factor. There are still three main issues to be solved when the transmission of high-speed differential signal is being considered. First, the electromagnetic radiation induced by the common-mode current can easily couple to the radio-frequency integrated circuits (RFICs) with significant interference. Second, caused by the frequency-dependent loss of material, the magnitude of high-frequency signal usually decreases larger than that of low-frequency signal, which degrades the quality of transmission. Finally, the co-simulation time for active and passive circuits keeps prolonging as the complexity of the system increases. In the first-year project, the design concept and experimental validation for the multi-pair common-mode filter will be established. In this way, the electromagnetic interference or radio-frequency interference due to the common-mode radiation can be solved. In the second year, a novel concept will be proposed to integrate both common-mode suppression and differential-mode equalization in the same structure. Finally, based on the estimation index of nonlinear system, a prediction methodology will be constructed to rapidly estimate the transmission performance of the differential system.高速差動信號傳輸信號完整度電源完整度電磁相容共模抑制技術差模等化器信號傳輸評估High-Speed Differential SignalingSignal Integrity (SI)Power Integrity (PI)Electromagnetic Compatibility (EMC)Common-Mode SuppressionDifferential-Mode EqualizationEstimation Method for Transmission Performance應用於先進高速差動系統中的信號完整度及電磁相容設計之關鍵技術
