Dissertação (Mestrado em Engenharia) - Universidade Federal do Maranhão, São Luis, 2007.http://tedebc.ufma.br:8080/jspui/handle/tede/429In digital measurement systems, signal conditioning circuits have the main functionality of adjusting analog signals for digital conversion. For maximizing the application of a measurement circuit or system, yet considering its integration in a single chip, these circuits must be programmable, in order to serve to different kinds of sensors with diverse output signal characteristics. The main functions of the signal conditioning circuit, in this case, are the amplification and dc level shift of the analog signal. In this master s thesis, an architecture of a signal conditioning integrated circuit with programmable gain and dc level shift, optimized in number of discrete components, using the switched capacitor technique is proposed. The proposed architecture allows the circuit use in differential and single-ended modes, with unipolar and bipolar signals. The design of an integrated circuit is carried out for implementing the proposed architecture using 0.35 mm TSMC CMOS technology, available in the ASIC design kit (ADK) of the Mentor Graphics, IC Nanometer software package.application/pdfAcesso AbertoSistemas em chipCondicionamento de sinais analógicosCircuitos integradosCircuitos ProgramáveisCapacitores chaveadosSistemas embarcadosMicroeletrônicaInstrumentação eletrônicaSystems on chipAnalog signal conditioningIntegrated circuitsProgrammable circuitsSwitched capacitorsEmbedded systemsMicroelectronicsInstrumentationCNPQ::ENGENHARIAS::ENGENHARIA ELETRICA::ELETRONICA INDUSTRIAL, SISTEMAS E CONTROLES ELETRONICOS::AUTOMACAO ELETRONICA DE PROCESSOS ELETRICOS E INDUSTRIAISDissertação
