Its current consumption does not depend on the process variations, the supply voltage and the temperature. This is achieved by using a replica biasing.

Simulations of schematic example confirm the proper operation of the presented comparator.","PeriodicalId":127983,"journal":{"name":"2017 XXVI International Scientific Conference Electronics (ET)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125363662","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 practice shows that one of the most common causes for remote monitoring compromise is the lack of skills for use of the equipment. An alternative representation of ECG is investigated in this paper. The aim is to provide an innovative approach for ECG transmission on long distance using a simple GSM module working in standard voice communication mode. The proposed procedure — \"sonification\" is tested with signals recorded from patients with cardiostimulator.

Conventional systems for PM monitoring have significant limitations, especially with respect to the costs for installation and maintenance. The number of these monitor stations is limited but PM concentration changes fast, non-linearly, within wide limits and depends on various factors. The large gradients in air quality, especially in urban areas, are a significant challenge for conventional measurement technologies. In recent years there has been a rapid development of compact, mobile low-cost measurement systems with better spatial coverage than that of traditional air quality systems. The present work is dedicated to the performance evaluation of commercial, off-the-shelf PM sensors. The main error sources in these sensors and the possibilities for their reduction are discussed.","PeriodicalId":127983,"journal":{"name":"2017 XXVI International Scientific Conference Electronics (ET)","volume":"122 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124620846","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 AC source is based on digital sine waveform generation, using the look-up table method. The generated sine waveform is furtherly amplified by AB class amplifier up to 260 Vpp. The voltage source constructed is connected to PC via USB interface. A simple testing program for the PC computer was also written. The test of the AC voltage source was performed by measurement of four layer AC electroluminescent panels in a setup consisted of PC computer, the voltage source developed, shunt resistor, optical fiber and spectrophotometer. The measurement of AC electroluminescent panel shows stable behavior of the source producing sine signal without apparently visible on the oscilloscope distortions of higher harmonics. The measured sample is of predominant capacitive character which is related to the strong influence of the dielectric layers.","PeriodicalId":127983,"journal":{"name":"2017 XXVI International Scientific Conference Electronics (ET)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125987281","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}

On this basis, generalized models of resonant inverters with and without reverse diodes are proposed. On this basis the novel compendious relationships between the most important internal inverter parameters are given. With these models, various inverter operating modes were investigated to search for optimal parameters with a defined target function. The whole processed information helps for good understanding and for organizing intelligent design, measurement and control of the inverters for technological applications (induction heating).","PeriodicalId":127983,"journal":{"name":"2017 XXVI International Scientific Conference Electronics (ET)","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132695989","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}
