We have been researching and developing a CMOS image sensor that has 2.8 μm x 2.8 μm pixel, 33-Mpixel resolution (7680 horizontal pixels x 4320 vertical pixels), 120-fps frame rate, and 12-bit analog-to-digital converter for “8K Super Hi-Vision.” In order to improve its sensitivity, we used a 0.11-μm nanofabricated process and attempted to increase the conversion gain from an electron charge to a voltage in the pixel. The prototyped image sensor shows a sensitivity of 2.4 V/lx•s, which is 1.6 times higher than that of a conventional image sensor. This image sensor also realized the input-referred random noise as low as 2.1 e-rms.
