Abstract : In order to extract and separate Action Potential AP signals according to their nerve fascicule origins, we propose a new architecture of a multipolar cuff electrode and an optimized integrated acquisition circuit. The proposed electrode has a specific layout of a large number of poles in order to both reject parasitic signals, such as electromyogram and provide a maximum of spatial selectivity for ENG signals. For one channel to be recorded, we need to consider seven recording sites. A low-noise integrated circuit ASIC has been designed in order to perform this first step of analog processing on each set of seven considered poles
