Abstract

An implantable IC receives power and commands wirelessly through an ASK inductive link, and transmits amplified neural data using a 433MHz FSK transmitter. A 10times10 array of platinum-tipped silicon electrodes interfaces with a flip-chip bonded 4.7times5.9mm² 0.5mum 3M2P CMOS 13.5mW IC containing 88 neural amplifiers, 9b ADC and spike detectors used for data reduction
