Abstract:
1. A solid-state imaging apparatus comprising: a pixel unit including a plurality of pixels arranged in a matrix and configured to generate an analog signal by a photoelectric conversion; and a read out circuit configured to convert the analog signal generated by the pixel unit into a digital signal, wherein the read out circuit comprises a plurality of analog circuits arranged each correspondingly to each of the plurality of pixels arranged in a column direction, a plurality of digital circuits arranged each correspondingly to each of the plurality of pixels arranged in a column direction and a plurality of logic circuits arranged each correspondingly to each of the plurality of pixels arranged in a column direction, and arranged between the plurality of analog circuits and the plurality of digital circuits, and wherein the plurality analog circuits are formed within a first semiconductor region of a first conductivity type and a second semiconductor region of a second conductivity type, the plurality of logic circuits are formed within a third semiconductor region of the first conductivity type and a fourth semiconductor region of the second conductivity type, the plurality of digital circuits are formed within a fifth semiconductor region of the first conductivity type and a sixth semiconductor region of the second conductivity type, the first to sixth semiconductor regions are electrically isolated from one another, and the number of elements included in each of the plurality of logic circuits is smaller than the number of elements included in each of the plurality of digital circuits.
