Modelling Measured 1/f Noise in Quanta Image Sensors (QIS)
Abstract
This study introduces a novel approach to model in-pixel source follower (SF) 1/f noise in Quanta Image Sensors (QIS) using a modified mobility-fluctuation model. It presents a systematic analysis where only mobility fluctuation is treated as the origin of 1/f noise, thus considering the correlated double sampling (CDS) effects. The model demonstrates a precise fit to experimental measurements across a range of temperatures and indicates that further reduction in read noise could be achieved through additional cooling, proffering significant insights for the enhancement of QIS in scientific applications.Keywords
