Towards a reconfigurable sense-and-stimulate neural interface generating biphasic interleaved stimulus

This work presents an eight channel neural stimulator interface based on an address event communication protocol. The system developed decodes, integrates and interleaves the spike patterns using a continuous interleave sampling (CIS) strategy, which drives a complex biphasic current waveform to a bipolar electrode configuration. This paper describes the basic concept, circuit design, simulation results and hardware implementation in a standard 0.35mum CMOS technology
