Implantable electronic medical devices that operate in closed-loop allow efficient neuro-modulation. Area and power are to be carefully balanced to improve the system autonomy and safety. New digital modulation schemes with implementation in the front-end signal acquisition such as Hadamard encoding and compressed sensing aim at efficiency improvement in multi-channel neural recorders.
