Photoelectric conversion apparatus, equipment

A photoelectric conversion apparatus comprising:

• a pixel configured to generate a pixel signal through photoelectric conversion;
• a signal line to which the pixel signal is output;
• a first transistor connected to the signal line;
• a second transistor connected to the signal line;
• a first switch connected to the first transistor;
• and
• a second switch connected to the second transistor,
• wherein the first transistor and the second transistor are connected to the signal line in parallel with each other,
• wherein a gate of the first transistor is connected to a first bias line,
• wherein a gate of the second transistor is connected to a second bias line,
• wherein the first bias line and the second bias line are electrically separated from each other, and
• wherein the first transistor limits a variable range of a voltage of the signal line.
