Abstract
This letter presents a novel readout architecture and its associated readout sequence for complementary metal-oxide-semiconductor (CMOS) image sensors (CISs) based on switch biasing techniques in order to reduce noisy pixel numbers induced by in-pixel source-follower transistor random telegraph signal noise. Measurement results done on a test image sensor designed with 0.35-μm CIS technology demonstrate an efficient reduction of noisy pixel numbers without a pixel performance decrease.
