Theoretical investigation of the noise performance of active pixel imaging arrays based on polycrystalline silicon thin film transistors

Purpose Active matrix flat‐panel imagers, which typically incorporate a pixelated array with one a‐Si:H thin‐film transistor (TFT) per pixel, have become ubiquitous by virtue of many advantages, including large monolithic construction, radiation tolerance, and high DQE. However, at low exposures suc...
