Signal processing transmitter for wireless implantable neural recording systems

Thanks to the fast growth of the technological sector and more precisely of the biomedical electronics, a total improvement of the living conditions of the human being and an appreciable increase of its longevity were carried out. This development allows creating implantable electronic devices for recording neural signals. This paper lies within the scope of acquisition and wireless transmission of these signals. We have developed a multichannel wireless implantable transmitter for digital neural signal processing after simultaneous recording through 16 channels. The simulation results attained are sufficient in terms of integrated design, low power consumption, low noise and high speed. These results confirm that this system is functional and has the aptitude to be extended to 32 channels and even 64.
