This paper analyzes some advantages of Silicon-on-Insulator (SOI) based photodetectors for bioluminescence imaging. It shows that SOI based sensors not only solve the bulk carriers problem, it can also act as a very selective spectral filter by acting as a resonant cavity, which is useful in application with a very narrow spectrum of interest, such as bioluminescence imaging. Then, the authors discuss...
This paper presents a fully Digital Pixel Sensor (DPS) front-end with a focus on the optimization of its operation and temperature dependence. The system relies on a new type of photodetector based on a hybrid MOS-PN structure displaying intrinsic light-to-time conversion. The photodetector as well as its front-end circuit are described as well as pulsed operation techniques that increase the Signal...
This paper presents a fully Digital Pixel Sensor (DPS) front-end with a focus on its noise modelling and analysis. The design relies on a new type of photodetector displaying an intrinsic light-to-time conversion. Avoiding the pixel level analog processing improves significantly the overall performances of the image sensor. The photodetector as well as its front-end circuit are described. The noise...
