Design of a multichannel wireless implantable neural signal processing transmitter

Increasing advances in neurology have created high demands of implantable multichannel electronic devices for recording neural signals. These implants acquire, treat and transmit wirelessly the nervous signals collected by a microelectrodes array to an external receiver. Our paper lies within the scope of recording and wireless transmission of these signals. We have designed a part of an implantable transmitter for neural signal processing after simultaneous acquisition with 16 channels. The results obtained are satisfactory in terms of integrated design, low power consumption, low noise and high speed. These results prove that the system is functional and has the ability to be extended to 32 channels and even 64 channels.
