The Channel Operating Margin (COM) comes up as a powerful tool for channel and physical layer designers to explore the design space at an early stage, as well as to optimize the channel physical parameters, thus overcoming the classic channel performance metrics such as eye diagram and BER. The analysis of the test cases proposed herein will guide through the use of COM and the channel analysis by investigating a 112 Gbps PAM4 chip-to-chip communication over a complex channel composed of a host board, a mezzanine connector, and a daughter card. Accurate analysis of these elements is carried out based on the connector characterization by measurements and full wave models; the PCBs, instead, are modeled as multiconductor transmission lines to resemble the typical configuration of coupled differential striplines. A comprehensive discussion of the COM results set relevant guidelines for a pre-layout analysis of such high speed communication channels.","PeriodicalId":189322,"journal":{"name":"2020 IEEE International Symposium on Electromagnetic Compatibility & Signal/Power Integrity (EMCSI)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127905819","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}

IVR enables product miniaturization but prone to RFI issues without proper design considerations due to high switching frequency. The proposed decoupling strategy allows flexible and low-cost platform designs. The critical design parameters, such as capacitance, capacitor number, and locations, are studied. The effectiveness of the proposed solution is validated with system-level measurements. These recommendations may help to mitigate radio frequency interference (RFI) due to IVR switching noise, relax IVR routing requirements, and eliminate the need of on-board shielding.","PeriodicalId":189322,"journal":{"name":"2020 IEEE International Symposium on Electromagnetic Compatibility & Signal/Power Integrity (EMCSI)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127961581","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 ability to quickly predict the risk of damage and/or upset early in the equipment and system development cycles is instrumental in guiding circuit and cable/connector assembly design to ensure economic and first time technical success during equipment qualification and system certification testing. This paper presents methods to predict damage and upset using circuit simulator based methods in situations ranging from simple to complex cable cross-section geometries that are common in defense/aerospace equipment qualification and certification test setups. Test data verifying the simulation process and capability is presented for situations where current waveforms are applicable.

Recently, a novel localization technique based on the Time Reversal Cavity (TRC) concept was proposed using only one sensor. In this paper, we discuss the concept of TRC and its application to the localization of EMI sources. We investigate the maximum peak field criterion to localize an EMI source in the cavity using one sensor. We show that the maximum peak field criterion in the presence of the cavity can be used to localize an EMI source with high accuracy. The performance of the proposed criterion is evaluated using the finite difference time domain method. Finally, we provide a proof of concept to show the ability of the time reversal concept in the localization of an EMI source in a cavity. Experimental results confirm that the proposed method can be used in practical EMC problems.","PeriodicalId":189322,"journal":{"name":"2020 IEEE International Symposium on Electromagnetic Compatibility & Signal/Power Integrity (EMCSI)","volume":"85 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126226312","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}

Because of this the generators run on a lower percentage of the rated load for most of their operation hours and are thus overdimensioned. The efficiency of generators is very poor when these are not running on full power. So, optimizing the power system such that it runs on a higher percentage of the rated load makes the system more efficient. In this paper measurement techniques used to determine the efficiency are researched. A system that uses a diesel generator is measured on-site, and analyzed using conventional power quality measurements and time-domain measurements in the millisecond range. The aim is to get more detailed insight in the behavior of the system and optimize the power supply system accordingly.","PeriodicalId":189322,"journal":{"name":"2020 IEEE International Symposium on Electromagnetic Compatibility & Signal/Power Integrity (EMCSI)","volume":"202 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125740277","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}

One such set of threats is nanosecond-scale transient effects generated by high-altitude electromagnetic pulses, for which the effect on the power grid is still being studied. Lightning surge arresters serve as the current grid protection against fast transients but are designed and modeled for protection against lightning and switching transients. Surge arrester response to faster transients is not well known. This work defines a scalable metal-oxide surge arrester model with specific consideration to frequencies attributed to fast transient overvoltages from electromagnetic pulses. Measurements using vector network analyzer sweeps at low and high bias as well as high-voltage I-V curve traces are presented to define arrester behavior and to parameterize it from measurement data. The proposed model is compared to the standard IEEE model for lightning arresters in this paper. Furthermore, model parameters are defined by scalable terms to be easily implemented for transmission-level devices. The scalable model enables enhanced assessment of protection levels and grid susceptibility against fast transients.","PeriodicalId":189322,"journal":{"name":"2020 IEEE International Symposium on Electromagnetic Compatibility & Signal/Power Integrity (EMCSI)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126989840","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}
