A triboelectric nanogenerator (TENG) was invented and is used to convert the mechanical energy to the electrical energy. The TENG is a promising candidate for the new transducers generation recommended for energy harvesting. It is used to harvest the mechanical energy with a great number of advantages. In this research, a new diagonal motion mode is proposed and is studied intensively in attached electrode mode using COMSOL finite element analysis. Diagonal motion mode offers a new degree of freedom which is the angle of motion allowing for further energy optimization. A new CAD tool is built based on semi-analytical equations derived from both COMSOL simulation results and theoretical framework. The tool optimizes the energy based on both the angle and the distance of motion in a few seconds which is very time efficient compared to the time consuming COMSOL simulations. The tool results show great consistency with the data obtained from time consuming COMSOL results.","PeriodicalId":112526,"journal":{"name":"2018 16th IEEE International New Circuits and Systems Conference (NEWCAS)","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124530910","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}

Florbetapir positron emission tomography (18F-AV-45 PET) is proven to be the most powerful imaging technique to investigate the deposition of amyloid plaques, one of the potential hallmarks of AD, signifying the onset of AD before it changes the brains structure. In this paper, we propose a novel classification algorithm to discriminate the patients having AD, early mild cognitive impairment (MCI), late MCI, and normal control in 18F-AV-45 PET using shearlet based deep convolutional neural network (CNN). It is known that the conventional CNNs involve convolution and pooling layers, which in fact produce the smoothed representation of data, and this results in losing detailed information. In view of this fact, the conventional CNN is integrated with shearlet transform incorporating the multiresolution details of the data. Once the model is pretrained to transform the input data into a better stacked representation, the resulting final layer is passed to softmax classifier, which returns the probabilities of each class. Through experimental results, it is shown that the performance of the proposed classification framework is superior to that of the traditional CNN in Alzheimer’s disease neuroimaging initiative (ADNI) database in terms of classification accuracy. As a result, it has the potential to distinguish the different stages of AD progression with less clinical prior information.","PeriodicalId":112526,"journal":{"name":"2018 16th IEEE International New Circuits and Systems Conference (NEWCAS)","volume":"122 25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122004900","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}

Due to the radiation-hardness requirements, the devices used for the development of such converters will have a voltage rating which is close to the converters’ input voltage. The voltage spikes generated during the hard-switching operation can affect the reliability of such low-voltage MOSFETs. A fixed and sufficiently small gate driver current for the high-side switch could be used to guarantee the reliable operation even in the worst-case conditions in terms of input voltage, output current, temperature and process variations. Nevertheless, this would result in a suboptimal efficiency in all the other working conditions. This work presents an integrated system than monitors in real-time the voltage stress, and adjusts the gate driver current to achieve maximum efficiency in all conditions, while ensuring compliance with the reliability specifications. A buck converter including the voltage peak detector and an adjustable gate driver current has been designed in a 130 nm technology, demonstrating the functionality of the voltage stress monitoring system.","PeriodicalId":112526,"journal":{"name":"2018 16th IEEE International New Circuits and Systems Conference (NEWCAS)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131737671","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}

Recently, several magnetic full-adder (MFA) designs based on spin-transfer torque (STT) and spin- Hall effect (SHE) magnetic random access memories (MRAMs) have been demonstrated. However, they consume higher write energy and occupy larger area. In this work, a novel MFA using differential spin-Hall (DSH) MRAM is proposed. The DSH- MRAM provides simultaneous switching of two PMTJ devices using SHE and generates complementary logic outputs. The single Hall metal (HM) shared by these PMTJ devices offers a very low resistance path for write operation. In this work, an external magnetic field (EMF) is used to assist the SHE current for PMTJ switching that eliminates the need for a STT current. A SPICE-compatible Verilog-A MTJ behaviour model of the proposed MFA is developed. The EMF-assisted DSH-MRAM requires a very short pulse (300 ps) of SHE current to switch both the PMTJs. The proposed MFA exhibits 65% less time, consumes 93% (18%) less write (read) energy, and saves 23% area compared to recent STT/SHE-MTJ based MFA designs.","PeriodicalId":112526,"journal":{"name":"2018 16th IEEE International New Circuits and Systems Conference (NEWCAS)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131063571","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}
