Abstract
The present invention relates to a system for artificial retinal prosthesis comprising a pixel array, a correlated double sampling unit, an analog-to-digital converter, a digital core, and a digital-to-analog converter. The system stimulates retinal cells row-to-row, and therefore can effectively reduce large transient currents and avoid unfavorable condition of power drop due to large transient currents.
