摘要
未来的视网膜假体需要更多的刺激点来恢复视力到独立活动、大字阅读和面部识别的水平。提出了一种1024像素视网膜刺激器的模块化设计。单个模块由64个驱动程序组成，用于优化系统。给出了64位驱动模块的电路设计和布局。该芯片目前正在0.35 μ m CMOS中制造。该芯片的数字控制器模块目前正在设计中，未来将与该驱动芯片集成
Towards a Modular 32 x 32 Pixel Stimulator for Retinal Prosthesis
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
