A CMOS x-ray line scan sensor which is used in both medical imaging and non-destructive diagnosis is designed. It has a pixel array of 512 columns ${\times}$ ¼ö½Ä À̹ÌÁö 4 rows and a built-in DC-DC converter. The pixel circuit is newly proposed to have three binning modes such as no binning, 2¡¿2 binning, and 4¡¿4 binning in order to select one of pixel sizes of 100¥ìm, 200¥ìm, and 400¥ìm. It is designed to output a fully differential image signal which is insensitive to power supply and input common mode noises. The layout size of the designed line scan sensor with a 0.18¥ìm x-ray CMOS image sensor process is 51,304¥ìm¡¿5,945¥ìm .
