In this study, we propose a CMOS chip for retinal prosthesis for high-rate stimulation. With an optimized control circuit, the current values of stimulation electrodes were set by only 36 clocks per electrode. We demonstrated operation at a frequency of 2.3 MHz on the prototype chip and a setup time of 17 μs for each electrode.
