CMOS active pixel and method of driving the same |
摘要 |
In a driving method of a complementary metal oxide semiconductor active pixel, timing of a transmission control signal and a reset control signal generated in a read-out section is performed in advance in a reset section. A potential wall between a photodiode area and a transmission transistor having a size corresponding to one generated in the read-out section is generated in the reset section in advance and the photodiode area is filled with charges. A dead region is reduced in the read-out section. In the reset section, the transmission transistor connecting a collection node to accumulate the signal charges generated from the photodiode and the floating diffusive node is turned on at least one time, and a difference between an initial voltage of the collection node and a voltage of the reset level of the floating diffusive node is reduced.
