Abstract

See full text

An AD conversion circuit with reduced comparator noise is disclosed. In one example, a solid-state image capturing device includes at least three stacked substrates, in which for each pixel block, a first substrate includes a photoelectric conversion unit that generates electric charges according to incident light, a transfer transistor, and a floating diffusion, a second substrate includes one comparator that compares a signal according to a voltage of the floating diffusion with a reference signal, a third substrate includes a code generation circuit that generates a code of a counter, a storage unit that stores the code, and a timing control circuit that controls a timing of storing the code in the storage unit, and the solid-state image capturing device further includes a pixel array in which a plurality of the pixel blocks is arranged.
