Programmable readout integrated circuit for an ionizing radiation sensor

摘要

Embodiments of the present invention provide a computer-implemented method for setting an amplification gain of a pixel array. Specifically, among other things, embodiments of the present invention provide a computer-implemented infrastructure comprising: receiving an electrical signal from an ionizing radiation source at one or more pixel sensors of a plurality of pixel sensors within the pixel array; setting an amplification gain of the electrical signal at a charge sensitive amplifier by turning a switch on or off, wherein the switch connects the at least one or more pixel sensors to a respective capacitor; scanning the pixel array to determine the ionizing radiation source intensity; and generating a gain control signal based on the ionizing radiation source intensity.
