Title
(EN) Imaging device and electronic apparatus with upper and lower substrates
Abstract
(EN)

The present technology relates to an imaging device that can reduce the size thereof, and to an electronic apparatus.

An upper substrate and a lower substrate are stacked. A pixel and a comparing unit that compares the voltage of a signal from the pixel with the ramp voltage are provided on the upper substrate, the ramp voltage varying with time. A storage unit that stores a code value obtained at a time when a comparison result from the comparing unit is inverted is provided on the lower substrate. The comparing unit is formed with a transistor that receives the voltage of the signal from the pixel at the gate, receives the ramp voltage at the source, and outputs a drain voltage. Accordingly, the imaging device can be made smaller in size. The present technology can be applied to image sensors.
