Document Type and Number:
WIPO Patent Application WO/2022/249736
Kind Code:
A1
Abstract:
[Problem] To provide an imaging device and an electronic apparatus in which a decrease in aperture ratio is avoided while achieving size reduction. [Solution] An imaging device comprising: a plurality of pixels each including a photoelectric conversion portion; a floating diffusion that outputs a voltage corresponding to charge obtained by photoelectric conversion in the photoelectric conversion portion in the pixel; a current amplification portion for amplifying a current corresponding to the voltage of the floating diffusion; a storage portion for storing a signal corresponding to the current amplified by the current amplification portion; an analog-to-digital converter which is provided for each area pixel consisting of two or more pixels among the plurality of pixels, and which converts signals stored in two or more storage portions corresponding to the two or more pixels in the area pixel, into digital signals; a plurality of stacked regions in which the plurality of photoelectric conversion portions in the plurality of pixels, a plurality of the analog-digital converters, a plurality of the floating diffusions, a plurality of the current amplification portions, and a plurality of the storage portions are disposed; and a signal transfer portion for transmitting and receiving signals between the plurality of regions. The region in which the plurality of photoelectric conversion portions in the area pixel are disposed and the region in which the plurality of current amplification portions are disposed transmit and receive the voltages of the plurality of floating diffusions via respectively corresponding signal transfer portions.
