Case Study of a Global Shutter CIS--Part 2: Parasitic Light Sensitivity

This article focuses on the parasitic light sensitivity (PLS) of a commercially available CMOS camera with a global shutter (with a storage node in the charge domain) and shared pixel architecture. The PLS is characterized as a function of both the wavelength and the incident angle of the incoming light. The measurement results are linked to...

Integration of 555 temperature sensors into a 64 × 192 CMOS image sensor

In this work, a novel approach for measuring relative temperature variations across the active area of a CMOS image sensor itself is presented. 555 Image pixels have been replaced by temperature sensors pixels (Tixels) in the same pixel array layer. Both sensors, pixels and Tixels, utilize the same readout structure to obtain the data. This...
