A scalable design for signal conditioning and digitization in implantable multi-channel neural sensors

We present the design of a neural data acquisition channel intended for multi-channel neural recording sensors. The design includes a neural signal conditioning stage and a digitization stage. As its power consumption is bellow 25 mu W and its size is of 0.0975 mm(2) this design is fully scalable to large micro-electrode arrays and suitable to implement systems including more than 100 channels.
