FOXFET in PIN diode strip detector [X-ray mammography]

Simulation and operation of a field oxide FET (FOXFET) biasing structure in a fabricated AC coupled single-sided strip detector are presented. The spatial distribution of the current density was explained by examination of the electric potential distribution and carrier concentration in the channel region of the FOXFET. The results presented confirm that incorporation of the FOXFET biasing structure is justified.
