Double feature, digital and analog, 5×5 SPADs single-photon camera

We present a fully reconfigurable single-photon camera, able to operate in both analog and digital modalities so to exploit the best performance out of the two features while solving usual issues that affect SPAD imagers. At first, one of the problems in SPAD arrays is the presence of hot pixels, with much higher dark count rate (DCR) compared to others, that impair system performance and are inevitable because of the presence of trapped charge...
