A Scalable Design for Signal Conditioning and Digitization in Implantable Multi-Channel Neural Sensors

Abstract

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 uW and its size is of 0.0975 mm2, this design is fully scalable to large micro-electrode arrays and suitable to implement systems including more than 100 channels.

Low‐Power Implantable Device for Onset Detection and Subsequent Treatment of Epileptic Seizures: A Review

“…Our research group has proposed several low-power implantable preamplifiers for neural signal amplification [41][42][43][44][45][46] and more recently, low-power implantable integrated devices for automatic seizure detection [19,20]. The experimental validation of our seizure detector prototype is under-way.…”
