Multi-Gate Source-Follower for Quanta Image Sensors (QIS)
Abstract
A multi-gate source-follower (MGSF) is introduced to simultaneously reduce 1/f noise and increase pixel conversion gain. 1/f noise generally deteriorates as the SF size becomes smaller although the conversion gain benefits from scaling. The MGSF can alter this tradeoff and make a low-noise high-conversion-gain QIS achievable. This work paves the way to further reduce the floating diffusion referred read noise in CMOS image sensors and QIS.Keywords
