Imageur CMOS ultra haute sensibilité

Abstract : A number of vision applications (medical imaging, astrophysics, …) require the detection of very low ligh levels (up to a few photons, or the single photon). Until recently, only one component can detect levels as low as the single photon: the photomultiplier. In recent years, it has been demonstrated the feasibility of designing avalanche diode using CMOS standard process. These advances allow to achieve high-resolution imaging and high sen-sitivity. The work in this thesis starts by the study of the behavior of the photon sensing element (SPAD) and finish by the design of the radout circuit of single photon avalanche photodiode. The second point of the work proposed in this thesis is a high-level model of SPAD followed by its readout circuit based on an anolg counter. The third line offers a novel readout method to enhance the readout dynamic range of pixel based on single photon avalanche photodiode. Finaly, A new readout circuit is proposed for SPAD based pixel. This readout circuit which is inspired from the simulated architectures will allow us to achieve our analog counter with the best performance.
