A very low column FPN and row temporal noise 8.9 M-pixel, 60 fps CMOS image sensor with 14bit column parallel SA- ADC

A 1.25-inch optical format, 8.9 M-pixel CMOS image sensor that employs a 4T pinned photodiode (P-PD) pixel and 14 bit column ADCs is reported. A 14 bit or 12 bit digital video signal is streamed out via 16-lane low-voltage, low-power differential serial output ports in 50 fps and 60 fps operations, respectively. Temporal noise floor of 2.8

_rms
and linear full-well of 27.8ke
