News and discussions about image sensors
Column ADCs is an interesting topic. JPL, Woody Yang, Photobit, Toshiba...So, it's quite a surprise to learn that the leaders now are Sony and Samsung.Interestingly, but Sony was inspired by the Micron R&D publication of 2003, CCD Workshop.
I'm not sure Sony and Samsung are leaders in that, but they certainly spend some efforts on column-parallel ADC improvements. On the other hand, Micron mostly uses 2 pipelined ADCs in its recent sensors after Photobit tried column parallel successive approximation ADCs a long time ago (few years is a long time in this industry).
