Illustrated in this project will be a new technique for the reduction of EMI disturbances in front end acquisition systems, that takes advantage of two standard, EMI sensitive amplifiers whose input stages react to radio frequency in a complementary way. A complete system will be designed utilising the exposed method, based on the digital acquisition and manipulation of data. This demonstrates an increased immunity with respect to each amplifiers used. This approach can be considered as an alternative to the existing written solutions that in general require the design of specialised, non standard, topologies, with the drawback of extended project times and dedicated non conventional analysis. The project illustrate the current problems, then describes some state of the art solutions and finally exposes the design steps that have led to the final result. This result is then laboratory tested to illustrate the power of the technique.
