Abstract
The present invention provides a light-driven retina chip capable of receiving a signal light and a background light, including: an array of photodiodes and a plurality of background light eliminating units. The array of photodiodes includes a plurality of photodiodes and a plurality of current amplifying circuits. The signal light is converted into an electric signal and the background light is converted into a plurality of background light currents. The photodiodes are correspondingly connected to the current amplifying circuits. The background light eliminating unit includes a plurality of background light sensing circuits and a plurality of current eliminating circuits. The current eliminating circuits are respectively and electrically connected to the photodiodes of the array of photodiodes. The background light currents generated by the photodiodes from the background light are eliminated by the background light eliminating units, thereby enhancing a dynamic range of the light-driven retina chip.
