In particular, the developed model provides a detailed investigation of magnitude and timing of the read-out signals and can therefore be exploited to perform reliable circuit-level simulations. The modeling approach used is strictly related to the physics of each basic microcell constituting the SiPM device, and allows the avalanche timing as well as the photodiode current and voltage to be accurately simulated. Predictive capabilities of the proposed model are demonstrated by means of experimental measurements on a real detector. Versatility of the proposed model is also confirmed.ELETTRONICOenConference paper10.1109/NEWCAS.2015.71820102-s2.0-84945156692https://ieeexplore.ieee.org/document/7182010FIS/05 - ASTRONOMIA E ASTROFISICA
