Albert Theuwissen publishes a review of ISSCC papers, starting from Sony BSI-GS CMOS imager with pixel-parallel 14b ADC: "One can make a global shutter in a CMOS sensor in the charge domain, in the voltage domain, but also in the digital domain. The latter requires an ADC per pixel (also known as DPS : digital pixel sensor). And this paper describes such a solution : a stacked image sensor with per pixel a single ADC."

Panasonic organic sensor: "The paper claims that the reset noise is lowered by a factor of 10, while the saturation level is increased by a factor of 10 (but the high saturation mode cannot be combined with the low noise level)."

Samsung 24MP CIS with 0.9um pixel: "All techniques mentioned are not new, but their combination for a 0.9 um is new."
