Abstract
A solid-state image sensor comprising a pixel array having a plurality of pixels, and a plurality of signal processing circuits each of which amplifies a signal of the pixel array, wherein each of the plurality of signal processing circuits comprises an operation amplifier having an input terminal and an output terminal, an input capacitance arranged between the input terminal and the column signal line, and a feedback circuit which connects the input terminal with the output terminal, wherein the feedback circuit is configured to form a feedback path in which a first and a second capacitance elements are arranged in series in a path connecting the input terminal to the output terminal, and a third capacitance element is arranged between a reference potential and a path connecting the first capacitance element to the second capacitance element.
