A Very Low Column FPN and Row Temporal Noise 8.9M-Pixel, 60fps CMOS Image Sensor with 14bit Column Parallel SA- ADC

摘要

A 1.25-inch optical format, 8.9M-pixel CMOS image sensor that employs a 4T pinned photodiode (P-PD) pixel and 14bit column ADCs is reported. A 14bit or 12bit digital video signal is streamed out via 16-lane low-voltage, low-power differential serial output ports in 50fps and 60fps operations, respectively. Temporal noise floor of (2.8e{sub}(rms)){sup}- and linear full-well of 27.8ke{sup}- were obtained at 60fps operation. Row temporal noise and column FPN are as small as (0.31e{sub}(rms)){sup}- and (0.36e{sub}(rms)){sup}-, respectively.
