A Neural Stimulation System Model to Enhance Neural Integrated Circuit Design

Lacking in the progression of neural stimulation probe, module, and integrated circuit design has been a system-to-device design approach, resulting in less than satisfying in-vivo results. The goal of this paper is neural integrated circuit (IC) design, including time-domain interaction with the electrode, tissue, and neural interfaces, which demonstrates system optimization prior to fabrication. The result of this work is a demonstration of a working CMOS multiplexer for neural stimulation, as well as a model of the multiplexer-electrode-neuron interface.
