pixel are not limited to a-Si technology or medical imaging and can potentially be used for high resolution digital A novel architecture for active pixel sensor (APS) arrays with angappliations usin cryaine repolycrystal only two thin film transistors (TFTs) is presented, and a new ilin tcologs.driving scheme for minimizing the threshold voltage metastability problem and increasing frame rate is discussed.Two transistor pixel architecture and operation The fewer number of on-pixel elements, and reduced pixel A Pixel architecture complexity, results in a smaller pixel pitch and increased pixel gain, and makes the presented APS architecture In the 2T APS architecture, TI operates as a switched promising for high resolution, high speed imaging modalities amplifier, integrating functions of both the READ and AMP such as digital mammography tomosynthesis.TFTs of the 3T design. The 3T APS architecture and the novel 2T pixel circuit architectures are shown in Fig. 1. Compared to the 3T pixel architecture, the READ (or row Introduction select) transistor has been removed from the pixel in the 2T
