Solid-state imaging device and electronic apparatus

摘要

There is provided a solid-state imaging device including an imaging unit including a plurality of image sensors, and an analog to digital (AD) conversion unit including a plurality of AD converters arranged in a row direction, each AD converter performing AD conversion of an electrical signal output by the image sensor. Each of the AD converters includes a comparator having a differential pair at an input stage, the differential pair including a first transistor and a second transistor, the first and second transistors are each divided into an equal number of a plurality of division transistors, and an arrangement pattern of the plurality of division transistors constituting the comparator in a predetermined column and an arrangement pattern of the plurality of division transistors constituting the comparator in an adjacent column adjacent to the predetermined column are different from each other.
