Quanta burst photography

Claudio Bruschini, Edoardo Charbon, Arin Can Ülkü, Shantanu Gupta, Mohit Gupta

Single-photon avalanche diodes (SPADs) are an emerging sensor technology capable of detecting individual incident photons, and capturing their time-of-arrival with high timing precision. While these sensors were limited to singlepixel or low-resolution dev ...

Compact Modeling of Charge Transfer in Pinned Photodiodes for CMOS Image Sensors

Christian Enz, Farzan Jazaeri, Assim Boukhayma, Raffaele Capoccia

In this paper, we propose a physics-based compact model of the pinned photodiode (PPD) combined with the transfer gate. A set of analytical expressions is derived for the 2-D electrostatic profile, the PPD capacitance, and the charge transfer current. The ...
