Abstract

A photoelectric converter includes a pixel array including a plurality of pixels, a capacitive coupling amplifier configured to amplify a signal output from the pixel array, and a delta-sigma AD converter configured to convert, into a digital signal, an analog signal output from the amplifier. The amplifier is formed by a plurality of first elements including an active element and a capacitive element. The delta-sigma AD converter is formed by a plurality of second elements including an active element and a capacitive element. A breakdown voltage of at least one of the plurality of second elements forming the delta-sigma AD converter is lower than a breakdown voltage of the plurality of first elements forming the amplifier.
