Abstract: PARISROC is a complete read out chip, in AMS SiGe 0.35 !m technology, forphotomultipliers array. It allows triggerless acquisition for next generationneutrino experiments and it belongs to an RandD program funded by the Frenchnational agency for research ANR called PMm2: ?Innovative electronics forphotodetectors array used in High Energy Physics and Astroparticles?ref.ANR-06-BLAN-0186. The ASIC Application Specific Integrated Circuitintegrates 16 independent and auto triggered channels with variable gain andprovides charge and time measurement by a Wilkinson ADC Analog to DigitalConverter and a 24-bit Counter. The charge measurement should be performedfrom 1 up to 300 photo- electrons p.e. with a good linearity. The timemeasurement allowed to a coarse time with a 24-bit counter at 10 MHz and a finetime on a 100ns ramp to achieve a resolution of 1 ns. The ASIC sends out onlythe relevant data through network cables to the central data storage. Thispaper describes the front-end electronics ASIC called PARISROC.
