Displacement Damage Test Report for the OMT1090 Optical Switch
The purpose of this study was to examine the displacement damage susceptibility of the OMT1090 optical switch manufactured by TT Electronics / OPTEK Technology Inc. and compare it to the results of the OPB847TXV.

Displacement Damage Induced Dark Current and Random Telegraph Signal in P-Type Deep-Trench Pinned Photogates
This study focuses on displacement damage induced dark current and Random Telegraph Signal (RTS) in STMicroelectronics P-Type photogate, a device moving away from the 4T Pinned-Photodiode, with a sensitive volume exclusively made of boron-doped P-type epitaxy, and collecting holes instead of electrons. Results show a typical trend for the shape of dark current and RTS degradation in CMOS Image Sensors with the exception that the measured generation rates seem 2 times smaller than typical literature values in irradiated silicon. Different hypothesis on the origin of this discrepancy are explored.
