In this case having applicability in energy harvest, the main approach for this circuit is to reduce the power dissipation and at the same time guarantee a stable of the reference voltage. This can be achieved through the utilization of MOS transistors which can work with a lower voltage then bipolar transistors. The reference voltage circuit present in this thesis can work with a supply voltage as low as 500 mV. In energy harvest systems besides the need to work with extremely low voltages, the sensitivity of the signals is very high, to temperature variation. So it was also important to work with an extended ranges of temperature. For this work it was also developed a temperature sensor so that it has applicability in various fields. The sensor works by currents generated by the bandgap voltage reference, having similar results to a dual slope integrating analogue-to-digital converter, although its operation and logic are quite different. The proposed solution is to implement a reference voltage generator powered by a voltage source of 500 mV, with a consumption of about 7 W. Having a temperature coefficient slightly below 74 ppm/ C and a temperature sensor with linearity quite satisfactory.Faculdade de Ciências e TecnologiaPaulino, NunoRUNSilva, João Gonçalo Clemente da2014-02-06T12:08:13Z20132013-01-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttp://hdl.handle.net/10362/11330enginfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2024-03-11T03:45:46Zoai:run.unl.pt:10362/11330Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-20T03:20:12.976077Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse
