Document Type and Number:
Japanese Patent JP5074808
Kind Code:
B2
Abstract:
A photoelectric conversion apparatus is disclosed. A photoelectric conversion apparatus includes a pixel array in which pixels including photoelectric conversion units are arrayed in a row direction and a column direction, a plurality of first column signal lines which are electrically connected to the pixels arrayed in the pixel array in the column direction, respectively, a plurality of column amplification units which amplify signals provided via the plurality of the first column signal lines, respectively, a power supply line which provides a power supply voltage to the plurality of column amplification units, and a plurality of second column signal lines which are electrically connected to output sides of the plurality of column amplification units, respectively. Each column amplification unit includes a current limiting unit which limits the flow of an excessive current to each of the plurality of second column signal lines.
