A clamp circuit clamps a gate voltage of the differential transistor. An output circuit performs a first operation in which a voltage based on the voltage at the gate of a pixel transistor is output to the gate of the differential transistor. The output circuit also performs a second operation in which in response to receiving a current from the differential transistor, a signal based on a result of a comparison between the gate voltage of the pixel transistor and the gate voltage of the differential transistor is output to the output node. In the second operation, a control unit in the output circuit controls a change in the drain voltage of the differential transistor to be smaller than a change in the voltage at the output node."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Photoelectric conversion apparatus and photoelectric conversion system","description":"In a photoelectric conversion apparatus, a pixel transistor and a differential transistor form a differential pair.
