To control this effect, electric field sensors are required. The purpose of the study is to minimize the error of a known sensor and to expand the spatial range of measurements by optimizing its sensitive elements. The constructive and mathematical models of a disk sensor of electric field strength are designed in this work. The methods for calculating electrostatic fields are used to study a single-axis electro-induction disk sensor of radius $R$ with sensitive elements in the form of circles of radius r, and an estimate of the calculation error due to field inhomogeneity is given. It is shown that the maximum of this error, depending on the size of the sensitive elements, can be less than 3% at distances to the field source less than R, which allows us to design qualitatively better sensors used in various measuring systems of wide application","PeriodicalId":141827,"journal":{"name":"2021 International Conference on Electrical Engineering and Photonics (EExPolytech)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129347472","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}

Typically, only considerations of monotonicity and routing complexity define the architecture choice. Herewith, different properties in terms of systematic error compensation are not taken into account. Systematic error compensation is achieved with so-called switching schemes. This research presents results of simulation for unary and binary switching schemes. The results show that the performance of binary switching schemes degrades with resolution increase. Therefore, for static nonlinearity improvement, binary switching schemes can be used instead of unary ones only at low resolutions (4–6 bits). In terms of dynamic performance, a binary switching scheme can provide a more compact layout by cost of a little loss in the dynamic range.","PeriodicalId":141827,"journal":{"name":"2021 International Conference on Electrical Engineering and Photonics (EExPolytech)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129663212","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}
