Abstract

Future retinal prosthesis requires more stimulation sites to restore vision to the level of independent mobility, large print reading and facial recognition. This paper presents a modular design of a 1024 pixel retinal stimulator. The individual module consists of 64 drivers, chosen to optimize the system. The circuit design and the layout of the 64-driver module are presented. The chip is currently under fabrication in 0.35-mum CMOS. The digital controller block for the chip is currently being designed and will be integrated with this driver chip in the future
