Document Type and Number:
Japanese Patent JP2022187477
Kind Code:
A
Abstract:
To provide an image sensor that includes a pixel including an internal capacitor.SOLUTION: An image sensor of the present invention includes a plurality of pixels. Each of the plurality of pixels includes: a photodetection circuit which includes a photodiode and generates a detection signal; and an analog-to-digital converter which converts the detection signal using a ramp signal. The photodetection circuit includes: a floating diffusion node which accumulates photocharges generated by the photodiode and has a parasitic capacitor; and an overflow transistor which electrically connects the floating diffusion node to a first internal capacitor of the analog-to-digital converter.SELECTED DRAWING: Figure 2
