A three-dimensional neural recording microsystem with implantable data compression circuitry

Olsson, Roy H.; Wise, Kensall

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 5.4mW at 3V. ©2005 IEEE.
