Due to the reusability of the silicone rubber socket, it is suitable for a reliable test. In addition, its electrical performance is compared with that of conventional solder balls. The performance of the two are compared using measurements in both frequency and time domains. Their eye diagrams are nearly identical at the data rate of 28Gbps, which is the data rate of a single channel in a 100Gbps transceiver IC that consists of 4 parallel channels.","PeriodicalId":130864,"journal":{"name":"2015 IEEE 24th Electrical Performance of Electronic Packaging and Systems (EPEPS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131242684","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}

A time step size used in a basic explicit leapfrog scheme becomes too small if there exist extremely-small reactances in a circuit. Because such small reactances are usually extracted from small meshes, the basic leapfrog scheme is not suitable for the simulation including electrically-small objects, such as small apertures on a conductor plane of a PDN. The proposed stabilized leapfrog scheme can remove instability related to the low reactances and enables to use a relatively-large time step size which is not limited by a numerical stability condition. The proposed method is applied to the transient simulation of an example PDN to demonstrate its accuracy and efficiency. Numerical results show that our approach successfully avoids the time step size limitation and can perform much faster simulation than existing solvers.","PeriodicalId":130864,"journal":{"name":"2015 IEEE 24th Electrical Performance of Electronic Packaging and Systems (EPEPS)","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122897373","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}

In these devices, the slew rate is suitably controlled, the communication scheme alternates data-bursts followed by power-saving states, the voltage swing and the common-mode level are reduced. To achieve these targets, a key role in voltage-mode output drivers is played by an internal voltage-regulator. The latter exhibits a rich dynamic behavior, with non-negligible effects on the transmitter outputs, that need to be carefully characterized. In this paper, a modeling strategy based on a few key enhancements of state-of-the-art solutions is presented, leading to compact and accurate models. The feasibility and strengths of the proposed approach are verified on a low-power high-speed voltage-mode driver.","PeriodicalId":130864,"journal":{"name":"2015 IEEE 24th Electrical Performance of Electronic Packaging and Systems (EPEPS)","volume":"130 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131599966","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}

A 3-D printer based on the Fused Diffusion Modelling (FDM) technology was employed to 3-D print the substrate material. The resonance frequency of the antenna shifts in response to the applied force which makes the configuration suitable for the wireless strain sensing application. The proposed antenna was designed for wearable electronics application such as health monitoring earrings. Hence it was designed in such a way that it maintains the Specific Absorption Rate (SAR) of the human head tissues within the assigned standard limits when placed near human replicating head.
