Embodiment Construction
[0020] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0021] The present invention is used for the artificial retina electrical stimulation pixel circuit of visual function restoration, such as figure 2 As shown, it includes a photodiode, a capacitor C1, a Schmitt trigger, a CMOS inverter, a charge and discharge control loop, and a stimulating electrode; the anode of the photodiode is grounded, and the external visible light is the input of the photodiode. After the external visible light image is focused by the eyeball, it irradiates the photodiode and forms a photocurrent on the photodiode. The cathode of the photodiode is connected to the first output terminal of the charge and discharge control circuit, and the second output terminal of the charge and discharge control circuit is a Schmitt trigger. The input terminal of the device, a capacitor C1 is connected between the input terminal of the...
