The lossy line should be equalized by different filter schemes to achieve the best performance of the route and to obtain a proper opening of the eye diagram. This paper emphasis the performance of an equalization filter variant considering the interconnect as a transmission line starting with synthesis of the filter and up to the fabrication of the test board. Applying on both electric and optics signaling, equalization is needed to avoid amplitude and phase distortion of the received pulse.","PeriodicalId":138347,"journal":{"name":"2017 IEEE 23rd International Symposium for Design and Technology in Electronic Packaging (SIITME)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129901305","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}

Usually, converters work in the sub-MHz range and naturally the questions of losses both in-core and in-winding appears. The present work provides a comparative analysis of winding losses in two types of planar transformer PCB stack structure. The study aims to analyze the influence of winding arrangement on a step-up planar transformer over the leakage inductance based on the magneto motive force. The results show the impact of losses on the full converter in two FR4 structure embodiments: one with the secondary on a single inner layer and the second with the winding in multiple layers. For this approach a planar core transformer was modeled for sub-MHz range (0.4–1.0 MHz) analysis.","PeriodicalId":138347,"journal":{"name":"2017 IEEE 23rd International Symposium for Design and Technology in Electronic Packaging (SIITME)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116919949","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}

This paper describes the internal architecture of a FPGA-based SoC with its components: networking interface (including a Web Server), data acquisition interface (through the on-board Analog-to-Digital converter) and configuration and control software.

The processors compete or collaborate each-other, sharing spatial or temporal information from a video stream. In this paper, a low-cost and low-power multiprocessor system is proposed for real-time image processing. The system is used in the feedback loop for visual servoing which aims to control a wheeled mobile robot (WMR) equipped with a robotic manipulator (RM). It is master-slave architecture, with cheap but performance processors. The goal is to ensure fast image processing in order to control the RM for recovering the rejected work pieces and sending them to the quality test for reprocessing. The modular and flexible structure of multiprocessor visual servoing system is presented and analyzed.","PeriodicalId":138347,"journal":{"name":"2017 IEEE 23rd International Symposium for Design and Technology in Electronic Packaging (SIITME)","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126344065","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}

Proof of concept mathemathical model of a modulation breaking the Shannon limit 打破香农极限的调制的概念数学模型的证明

A modulation grouping time domain overlapping symbols is proposed, in order to utilize oversampling. Overlapped symbol groups are decoded with the help of a system of equations, as each symbol has a slightly different time position. Their values can thus be distinctively detected with a low error probability. The Shannon limit is considered in a complete form, i.e. error probability, beside bandwidth and signal to noise ratio determine the maximum rate of a channel. The simulation gives a rate about four times the Shannon limit without considering bits to be wasted on synchronization, which are not considered in the Shannon limit either. The modulation needs time synchronization like most digital modulations, e.g. OFDM, but there are enough bits left for it without falling behind the Shannon limit. The result suggests a new channel limit theorem is needed and more research has to be done on reaching it by oversampling the signal relative to the channel bandwidth.","PeriodicalId":138347,"journal":{"name":"2017 IEEE 23rd International Symposium for Design and Technology in Electronic Packaging (SIITME)","volume":"181 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132907138","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 measurement system makes sure the measured voltages, representing the magnetic field B(t) and field intensity H(t), are in-phase in order to correctly obtain the losses. This is achieved through the use of two cascaded low-pass filters, whose cut-off frequencies are equal to the fundamental frequency. The performed experiment proved that the measured voltages are inphase and they can be used to correctly obtain the losses. The results are compared with situations where the two quantities are slightly out-of-phase, and the relative errors are evaluated.","PeriodicalId":138347,"journal":{"name":"2017 IEEE 23rd International Symposium for Design and Technology in Electronic Packaging (SIITME)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133666932","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}
