The 8B/10B encoding scheme has been used in the HDMI. Because the eye diagram heavily depends on the bit patterns, the encoded PRBS patterns should be considered when the resultant eye diagram is obtained. Likewise, the 8B/10B encoding scheme must also considered when the eye diagram is estimated. An eye diagram estimation method finds the worst contour of the eye diagram using partial information. This can be done in significantly reduced testing time by using a SBR, as opposed to all of PRBS patterns. In high-speed IC tests, the ICs are interconnected with an automated test environment (ATE) by test sockets. Since the resultant eye diagram consists of 8B/10B encoded signal, the eye diagram should be estimated considering the encoding scheme. This paper considers the mapping scheme of Lattice RD 1012. In conclusion, the eye diagram of the 8B/10B encoded signal by Lattice RD 1012 is estimated using the SBR of the silicone rubber socket under the various compression effect. The estimated eye diagram and simulated eye diagram of the encoded PBRS patterns are nearly identical. Therefore, the proposed eye diagram estimation including the conventional 8B/10B encoding scheme is verified by comparing with that of PRBS patterns.","PeriodicalId":326016,"journal":{"name":"2016 IEEE International Symposium on Electromagnetic Compatibility (EMC)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115844808","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}

The SAR is used to evaluate the radio frequency (RF)-induced heating of the devices during magnetic resonance imaging (MRI). Because multi-component orthopaedic hip replacement systems have many combinations of components with various designs and sizes, it is computationally intensive, and almost impossible, to evaluate the SAR and the corresponding temperature rise for each possible combination and configuration. In this study, an effective searching strategy and a computational simulation model are developed to evaluate the factors associated with induced SAR in the tissue near an orthopaedic hip replacement system, and to find the “worst case” peak SAR for all possible combinations. The finite-difference time-domain (FDTD) was used to calculate the peak SAR for a typical hip replacement system inside the American Society for Testing and Materials (ASTM) phantom for both 1.5 Tesla (T) and 3T MRI systems. The results indicate that the stem and screw lengths are the most important factors influencing the peak SAR for both field strengths, 1.5T/64 MHz and 3T/128 MHz, respectively. The peak 1 gram averaged SAR reaches 216 W/kg and 103 W/kg for 64 MHz and 128 MHz, respectively. We also found that shortest stems, and the longest screws, typically induce higher peak SAR.","PeriodicalId":326016,"journal":{"name":"2016 IEEE International Symposium on Electromagnetic Compatibility (EMC)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134033795","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}

The proposed design is realized by using only two enhanced coupled C-shaped defected ground structures (DGSs) with a long bridge to achieve the wideband common-mode noise suppression. The equivalent circuit model of two coupled LC resonators is also established with good agreement to the full-wave simulation and measurement results. A sample board is designed and fabricated on a printed circuit board (PCB) with FR4 substrate. It is proved that the differential-mode insertion loss is within -3 dB from DC to 12 GHz. Common-mode noise can be reduced over 10 dB from 3.7 GHz to 10.8 GHz in the frequency domain, and approximately 42% of amplitude in the time domain. Moreover, the fractional bandwidth of the stopband can reach 98%, and the filter size is only 0.3 λg × 0.3 λg, where λg is the wavelength of the stopband central frequency. To our knowledge, this is the first common-mode filter using an enhanced coupled mechanism for the high-speed signals to extend the stopband, and it is also a simple geometric structure with the largest fractional bandwidth and the most compact size on a PCB.","PeriodicalId":326016,"journal":{"name":"2016 IEEE International Symposium on Electromagnetic Compatibility (EMC)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116041572","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}
