Proposed method does not imply the necessity of usage of various filtering methods, however, requires the applying of reference signal. Proposed processing of sine curves with noise components implies separate calculation of inner product of analyzed signals with the reference sine signal for the purpose of their initial phase estimation. Paper also contains illustration and analysis of the influence of normally distributed noise on the accuracy of cross-correlation function estimation for various durations of analyzed signals. Main sources of inaccuracy that lead to bias in estimated value of dissipation factor are also listed and discussed. The results of comparative analysis of accuracy of phase shift and dissipation factor estimation, based on simulations made for generated model signals by means of applying the proposed modification of the cross-correlation method and the conventional crosscorrelation method, are also given.","PeriodicalId":115140,"journal":{"name":"2020 IEEE KhPI Week on Advanced Technology (KhPIWeek)","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134391768","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}

There are presented the allowable electrical characteristics in a temperature range of 300–360 K. Numerical simulation has been shown that usage of proposed structures provides permissible values of threshold voltage, sub-threshold swing, drain-induced barrier lowering, drain current and Ion / Ioff ratio. A comparison of working characteristics of simulated structures allows us to conclude that SOI GAA NW-FET had better positions than SOI TG FinFET structures.","PeriodicalId":115140,"journal":{"name":"2020 IEEE KhPI Week on Advanced Technology (KhPIWeek)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130292243","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}

These neural networks are used for interpolation and approximation of experimental data. To do this, it is constructed and trained neural networks of direct distribution. The training is carried out by the method of back error propagation. The data set was generated based on the results of the experiment. For testing, all networks received the same dataset that was not used during the training but was known from the experiment.
