用于X射线传感器的处理电路
摘要：
提供了一种用于X射线传感器的以供至少采集第一像素的第一像素信息和第二像素的第二像素信息的处理电路。所述处理电路包括放大器(112)、反馈回路(113)和第一采集装置(111)。通过在X射线传感器的外围应用反向的非线性(125)为像素或像素电路(100，200)中的非线性提供了补偿。处理电路(110)可以提供像素电压和/或像素电荷的副本。就像素电荷而言，可以补偿像素电容的非线性特征。
摘要（英）：

A processing circuit for an X-ray sensor for collecting at least a first pixel information of a first pixel and a second pixel information of a second pixel is provided. The processing circuit comprises an amplifier (112), a feedback loop (113) and a first collecting device (111). It is provided a compensation for a non-linearity in the pixels or in the pixel circuits (100, 200) by applying an inverse non-linearity (125) in the periphery of the X-ray sensor. A processing circuit (110) may provide a copy of a pixel voltage and/or of a pixel charge. In the case of pixel charge a non- linear characteristic of a pixel capacitance may be compensated.
