摘要：
In a photoelectric conversion device including a photodiode and a current mirror circuit, a diode-connected transistor is provided in parallel with the photodiode. The transistor serves as a leakage path for rapidly discharging charge stored in the gate capacitance in the current mirror circuit. Thus, the response speed of the photoelectric conversion device is increased, and output of an abnormal value is reduced.
