Digital system design for wireless bionic neural link

Abstract

This paper describes the digital system for neural recording and stimulation, which is designed for bionic neural link (BNL). The digital design for neural recording converts the multi-channel neural spikes as one trigger command and sends out via wireless channel. The digital stimulation design generates the adaptive arbitrary waveform to stimulate the muscle when a trigger signal comes. The digital system is designed in a 0.18 μm CMOS process and the power of the digital system for neural recording and stimulation chip is 80 μW and 130 μW with supplying by 1.8V voltage, respectively.
