A 4K2K 480 fps global-shutter CMOS image sensor has been developed with super 35 mm format. This sensor employs newly developed gain-adaptive column ADCs to attain a dark random noise of 140 μV <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">rms</sub> for the full-scale readout of 923 mV. An on-chip online correction of the error between two switchable gains maintains the nonlinearity of output image within 0.18 %. The 16-channel output interfaces with 4.752 Gbps/ch are implemented in 2 diced logic chips stacked on a sensor chip with 38K micro bumps.
