Photoelectric conversion device |
摘要 |
A photoelectric conversion device formed on a single semiconductor substrate, including: a plurality of photoelectric conversion elements; a read-out circuit including a switch for reading out analog signals from the photoelectric conversion elements; a buffer circuit for driving the switch; and a logic circuit for processing digital signals. A first semiconductor area to which a ground level for the buffer circuit is supplied and a second semiconductor area to which a ground level for the logic circuit is supplied are electrically separated from each other.
