A 16-layer network with two regression heads provided the best regression model for both configurations, manifesting the trained model can accurately extrapolate the mean of maxima in the other frequency steps that are not used in the training data set.

In the first method (M1), the magnitude of the known TF at the extreme frequencies is kept constant for all the unknown frequencies. The second method (M2) uses a linear extrapolation of the magnitude of the known TF at the highest frequency and a decade earlier. The third method (M3) uses the known portions of the TF to extract its minimum phase function, using the discrete Hilbert transform integrals. The performance of the three methods is analyzed for different rise times of the incident field and with practical signal-to-noise ratio (SNR) at the oscilloscope input. For noise-free signals, M1 and M2 outperform M3 for almost all the considered rise times. On the other hand, the three methods produce errors within the same order of magnitude for noised signals. Given the complexity and computational time required to implement M3, it is suggested that M1 or M2 are used in practical applications.","PeriodicalId":100625,"journal":{"name":"IEEE Letters on Electromagnetic Compatibility Practice and Applications","volume":"4 1","pages":"16-20"},"PeriodicalIF":0.0,"publicationDate":"2022-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67872934","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the short distance channels can significantly affect overall signal integrity (SI) performance. Thus, this letter focuses mainly on analysis and design of signal interconnection on FPC cable and COF package in terms of impedance matching and crosstalk. By optimizing the FPC cable design to mitigate crosstalk as well as insertion loss, the opening area of eye diagram was found to be improved more than twice over the previous one. In addition, through adjusting process of on-die capacitance of electro-static discharge (ESD) protection circuitry in the input stage of a high-speed circuit block, the created parasitic inductance of COF package trace was observed to be compensated. This optimization process can improve greatly system performance by widening the input eye opening. Finally, we propose channel design considerations and design guidelines to ensure better SI performance in flexible channels on high-speed intra-panel interface for large-size liquid crystal display (LCD) TV applications.","PeriodicalId":100625,"journal":{"name":"IEEE Letters on Electromagnetic Compatibility Practice and Applications","volume":"4 1","pages":"11-15"},"PeriodicalIF":0.0,"publicationDate":"2022-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68044004","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
