Abstract

In this work, the 1/f noise of the source follower (SF) in pinned-photodiode CMOS pixels is characterized. It is found that the 1/f noise in these pixels is actually due to a very limited number of traps and results in a random telegraph signal (RTS). It is pointed out how the correlated-double sampling (CDS) reacts on this RTS. The temperature dependency of the imager read noise revealed two mechanisms of RTS during CDS
