  • Abstract
    This paper describes a retinal prosthetic device using a pulse frequency modulation (PFM) based photosensor with a standard CMOS technology and its modification to stimulate retinal cells effectively. A 32x32-pixel PFM photosensor array chip have been fabricated using 0.6 μm CMOS technology and demonstrated the improved functions.
