Abstract
A fully implantable system for BCI studies has been designed around a state of the art ECoG recording ASIC. The device is able to record on 64 electrodes with selectable gain and sampling frequency, with less than 0.7µVRMS input referred noise in the [0.5Hz – 300Hz] band. It is powered remotely through an inductive link at 13.56MHz, communicates wirelessly on the MICS band at 402MHz with a custom designed base station connected to a PC and complies with the regulations applicable to class III AIMD. The architecture and design choices are detailed and the performances are compared with respect to other existing systems.
