The most commonly used pixel structure in Integrated Circuit (IC) technologies is the three-transistor pixel structure (3T). This structure consists of a pixel, a reset transistor, as source follower and a pixel select transistor. It has been shown that this structure exhibits the best performance and reliability, although no real in-depth analysis has been previously presented. In this paper, a thorough analysis and optimization of this structure has been done. Simulation results depicting this optimization for the AMS S35D4M5 process is provided to support the mathematical contribution of this paper.
