PARISROC, an autonomous front-end ASIC for triggerless acquisition in next generation neutrino experiments

The ASIC PARISROC, which stands for “Photomultiplier ARray Integrated in SiGe Read Out Chip”, is a complete read out chip in AustriaMicroSystems (AMS) SiGe 0.35 µm technology. It integrates 16 independent channels to provide charge and time measurements. The PMm
²
project, funded by the French national Agency for Research (ANR), has proposed a new system of “smart photo-detectors” composed by sensor and read-out electronics dedicated to next generation neutrino experiments. In this context the ASIC PARISROC has been developed as a SoC (system on chip) that processes the analog signals, self triggering and digitizing internally the data.
