From 2009-2012, a ban on the marketing of incandescent domestic bulbs ranging from 100 down to 25 watts is in place in the EU. Electricity savings have been taken into account, but unfortunately, no account has been taken of the damage the LED lamps have on the human health. The paper reviews the negative impact that LED lighting has on the human organism and offers compromise solutions.","PeriodicalId":374877,"journal":{"name":"2018 IEEE XXVII International Scientific Conference Electronics - ET","volume":"388 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131418996","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 methodology is illustrated by analysis, sizing and simulation of current mirror operational transconductance amplifier (OTA) implemented in 16nm ultra-deep submicron CMOS technology. For this purpose, first the basic parameters and characteristics of the 16nm CMOS transistors are discussed and presented by charts. Next, an example of designing the current mirror OTA is developed. The relations between the basic design and the circuit parameters of the OTA are analyzed. Design considerations for sizing the circuit in 16nm CMOS technology are discussed and an appropriate sizing methodology is proposed. An illustrative example is presented. The results from sizing and simulation of the examined current mirror OTA are analyzed and generalized.","PeriodicalId":374877,"journal":{"name":"2018 IEEE XXVII International Scientific Conference Electronics - ET","volume":"177 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127293871","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}
