Abstract
The present invention provides a solid-state imaging apparatus that can significantly reduce kTC noise by using a negative feedback amplifying circuit. A solid-state imaging apparatus includes a pixel unit including a plurality of pixels arranged on a semiconductor substrate in a matrix, the pixel unit including, for each column, a source line and a column signal line, each of the plurality of pixels including: a photoelectric conversion unit that generates a signal charge corresponding to incident light; a storage unit storing the signal charge; a reset transistor; an amplifying transistor; and a cutoff transistor, wherein the amplifying transistor and the cutoff transistor form a negative feedback amplifying circuit. With this configuration, kTC noise can significantly be reduced.
