Abstract

A 256-site microsystem comprises 4 neural recording arrays with integrated amplification and multiplexing circuitry and an implantable spike detection ASIC. The spike detector compresses the amount of neural data by 92%, increasing the total number of channels recorded wirelessly from 25 to 312. The implantable circuitry consumes 5.4 mW at 3 V.
