Abstract
An image sensor including a pixel array section in which a plurality of pixels including photoelectric conversion units is disposed, and a comparator that compares an analog pixel signal output from the pixels to a predetermined reference signal, and outputs a comparison result according to a signal level of the pixel signal. The comparator includes differential pair transistors, a first load transistor connected in series with a first transistor of the differential pair, and a second load transistor connected in series with a second transistor of the differential pair. The first transistor of the differential pair accepts a signal obtained by combining the pixel signal and the predetermined reference signal as a gate input, the second transistor of the differential pair accepts a predetermined voltage as a gate input. In addition, a capacitance unit is connected between a common connection node of the first transistor of the differential pair and the first load transistor, and a node of the predetermined voltage.
