CHARGE INJECTION COMPENSATION FOR DIGITAL RADIOGRAPHIC DETECTORS

Embodiments of DR detector methods and/or apparatus for charge compensation can provide charge injection and/or at least one charge injection circuit that can temporally cancel charge injection to readout circuits resulting from positive (and/or negative) transitions of gate lines for pixel signal readout. In certain exemplary embodiments, DR detector imaging array methods and/or apparatus can provide variable charge injection levels (e.g., voltage or capacitance), variable Tau (e.g., resistance or capacitance), and/or multi-charge injection with staggered timing (e.g., using voltage and/or capacitance steps). In certain exemplary embodiments, DR detector imaging array methods and/or apparatus can provide charge injection compensation on ROIC on mask block basis. In exemplary embodiments, DR detector imaging array methods and/or apparatus can provide voltage reset off-set in readout circuits (e.g., ROICs).
