PHOTOELECTRIC CONVERSION DEVICE, PHOTOELECTRIC CONVERSION SYSTEM, AND MOVING BODY - A simplified explanation of the abstract
This abstract first appeared for US patent application 18352371 titled 'PHOTOELECTRIC CONVERSION DEVICE, PHOTOELECTRIC CONVERSION SYSTEM, AND MOVING BODY
Simplified Explanation
The patent application describes a photoelectric conversion device.
- The device includes a photoelectric converter, which converts light into electrical charges.
- There is a first node that receives these charges from the photoelectric converter.
- An amplification transistor is present, which generates a signal based on the voltage of the first node.
- A first transistor controls the connection between the first node and a second node.
- A second transistor controls the connection between the second node and a third node.
- When the first transistor is conductive, a first capacitance is added to the first node.
- When the second transistor is conductive, a second capacitance is added to the second node.
- The second capacitance is larger than the first capacitance.
Original Abstract Submitted
A photoelectric conversion device includes a photoelectric converter, a first node configured to be supplied with charges from the photoelectric converter, an amplification transistor configured to output a signal corresponding to a voltage of the first node, a first transistor configured to open/close a path between the first node and a second node not included in a path from the photoelectric converter to the first node, and a second transistor configured to open/close a path between the second node and a third node. A second capacitance which is added to the second node when the second transistor is set in a conductive state is larger than a first capacitance which is added to the first node when the first transistor is set in a conductive state.
