A 33Mpixel 120fps CMOS image sensor using 12b column-parallel pipelined cyclic ADCs

There has been increasing demand for high-reality video systems. Thus, there has been research and development into ultra-high-definition television (UDTV) schemes for the next-generation television broadcasting system called "Super Hi-Vision" (SHV). This system aims to improve viewing experience using higher-resolution pictures. A pixel count of 7680x4320 and frame rate of 120fps are defined as full-spec parameter values for the SHV video signal. The total pixel data output rate of full-spec SHV image sensors will be 48Gb/s or greater. Several image sensors have been developed for UDTV or digital cinema applications, but they still do not fulfill SHV specifications.
