S?o propostas duas arquiteturas de amplificadores program?veis por pulsos, sendo uma baseada em componentes discretos e outra baseada em capacitores chaveados. A partir de requisitos de opera??o definidos para o estudo, s?o definidos par?metros e realizadas simula??es para a valida??o das arquiteturas. Posteriormente, o software e o circuito s?o desenvolvidos e testados. ? realizada a avalia??o dos circuitos referentes ?s duas arquiteturas propostas, e a partir disso, ? selecionada uma arquitetura para que seja aperfei?oada e permita o desenvolvimento de um circuito integrado em um trabalho futuro. / This work deals with the research and development of a Pulse Width Programmable Gain Integrating Amplifier. Two Pulse Width Programmable Gain Amplifier architectures are proposed, one based on discrete components and another based on switched capacitors. From the operating requirements defined for the study, parameters are defined and simulations are carried out to validate the architecture. Subsequently, the circuit and the software are developed and tested. It is performed the evaluation of the circuits regarding the two proposed architectures, and from that, an architecture is selected to be improved, aiming the development of an integrated circuit in a future work.
