INTEGRATING PIXELS AND METHODS OF OPERATION |
| 摘要 |
A pixel cell includes a first integration capacitor, a second integration capacitor, a photo detector and a transistor. The first integration capacitor includes a first lead operatively coupled to the photo detector. The second integration capacitor includes a first lead. The transistor is operatively coupled between the leads of the first and second integration capacitors for enabling current flow between the photo detector and the second integration capacitor only once a threshold voltage is met on the first integration capacitor. |

1. A pixel cell comprising:
a first integration capacitor with a first lead thereof operatively coupled to a photo detector; a second integration capacitor with a first lead; and a transistor operatively coupled between the leads of the first and second integration capacitors for enabling current flow between the photo detector and the second integration capacitor only once a threshold voltage is met on the first integration capacitor. |
