—This paper presents a complete 256-electrode retinal prosthesis chip, which is small and ready for packaging and implantation. It contains 256 separate programmable drivers dedicated to 256 electrodes for flexible stimulation. A 4-wire interface is employed for power and data transmission between the chip and a driving unit. Power and forward data are(More)
—This paper presents a highly flexible and complete 256-electrode retinal prosthesis chip, which is small and ready for packaging and implantation. The chip contains 256 separate programmable drivers each of which is dedicated to its own electrode for flexible stimulation. The stimulator possesses a wide range of stimulation features, supporting various(More)
The proposed low-power bandgap reference voltage circuitry is specially designed for a temperature sensor of a retinal prosthesis. Retinal prosthesises have great potential for restoring vision to patients suffering from age related macular degeneration (AMD) and retinitis pigmentosa (RP). Here a circuit is proposed and implemented on 65 nm IBM CMOS(More)
