Retinal prostheses are being developed worldwide to help restore partial vision in patients suffering from eye diseases such as retinitis pigmentosa (RP) or age-related macular degradation (AMD). This paper presents a flexible electrode driver using 65 nm CMOS process for a 1024-electrode epiretinal prosthesis. The electrode driver is part of the implant device which is used to deliver electrical...
This paper presents a fully flexible stimulator using 65 nm CMOS process for a 1024-electrode epi-retinal prosthesis. The stimulator can select any number of electrodes at any time and also supports both mono-polar and multi-polar stimulation. Furthermore, the stimulator supports a wide range of stimulus parameters. A novel feature is that the electrode driver operates in an alternately pull-push...
