Comparison of two optimized readout chains for low light CIS

Christian Enz, Assim Boukhayma

We compare the noise performance of two optimized readout chains that are based on 4T pixels and featuring the same bandwidth of 265kHz (enough to read 1Megapixel with 50frame/s). Both chains contain a 4T pixel, a column amplifier and a single slope analog ...
