Photoelectric conversion device and imaging system |
摘要 |
A photoelectric conversion device comprises: a clipping unit including a MOS transistor which has a source connected to a signal line and a drain being connected to a power supply, and the clipping unit clipping an electric potential of the signal line to an electric potential corresponding to an electric potential of the source; a holding capacitance which has a first electrode and a second electrode, the first electrode being connected to a gate of the MOS transistor, and the holding capacitance holding at least a voltage transferred to the signal line while the charge-voltage converter has been reset; and a shift unit which shifts an electric potential of the second electrode in a direction such that the electric potential of the second electrode comes close to a level to be transferred to the signal line while the charge-voltage converter has been reset.
