The importance of designing an AIO (Operational Amplifier Instrumental), is the need for development and production of electronic elements that help mioelectriaca interface, which without relying on sources of power or high power, you can control devices with the basic movements of human beings, through one of its articulated members, for this is required to have built an operational amplifier - instrumental. The most commonly used to date are two stages, comprising a differential input and an inverter output, they even do not have cleaning steps, filter, frequency and length of the signal to be criminalized for certain operations and actions basic with focus on design aspects that minimize noise and voltage amplifier.
The investigation started with a modeling and design of components filters and noise reduction with AIO, capturing the signal on a channel, to go climbing in complexity and operability, all supported by an experimental analysis and supported by the frame CDIO (conception, design, implementation and operation). a first logical model of a manipulated with some muscle prototype is developed, this provides a platform for the movement of a servomotor and controlling at least 2 possible moves, in future work they will be documented and managed through a software that validates the significant reduction noise. It must acquire a greater understanding and knowledge of noise, electromagnetic interference, or EMI and its causes as it can help in the later stage of the processing chain, which is the removal or dissipation, so it plans to allocate time to better noise knowledge and study of procurement systems aimed at their reduction..
