nxn Stimulator and Reader Design for Retinal Prosthesis using Multiplexing Technique and CMOS Technology

Serially received multiplexed pixels of an image are decoded and scanned on the probes array to stimulate the retina to reproduce the image. This paper presents a retinal stimulator (RS), which needs only six interface wires irrespective of array size. RS decodes the time-multiplexed pixels of the image and scans them on the probes array. RS doesn´t need address to route the pixels. It is a bidirectional device that can also retrieve responses from retina as a reader and sends out multiplexed readings through reverse telemetry
