PHOTOELECTRIC CONVERSION APPARATUS, METHOD OF DRIVING THE PHOTOELECTRIC CONVERSION APPARATUS, FOCUS DETECTION SENSOR, AND IMAGING SYSTEM

摘要

Provided is a photoelectric conversion apparatus, including: a sensor cell unit including a photoelectric conversion unit, an amplification unit, a select switch, and a reset switch, the amplification unit including an input node and an output node; an output line; a signal processing unit; and a control unit. The output node is electrically connected to the signal processing unit via the select switch and via the output line in this order. The input node is electrically connected to the photoelectric conversion unit, and is electrically connected to the signal processing unit via the reset switch and via the output line in this order. The control unit controls the reset switch and the select switch to be both in a conductive state in a predetermined period.
