In recent years, besides concerning about the noise analyzation, the signal digitization is also a very important research spot in the research field of low noise CMOS image sensor. A 12bit, 10Msps pipeline ADC is presented which can be used as a chip-level analog-to-digital converter in a low noise CMOS image sensor, and it was taped-out in the 0.5μm CMOS standard process. Finally, by using of this ADC, an analog-output low-noise CMOS image sensor achieves analog-to-digital convert in a PCB test board, and based on an independent development image-forming system, this test board achieved a very good imaging test. The imaging result shows that this ADC can be used as a chip-level ADC of a low-noise CMOS image sensor.
