The Orsay group has been designing highly integrated multi-channel readout ASICS for reading out detectors (MaPMTs,SiPMs,RPCs..) for ILC calorimetry or LHC luminometry. The chips MAROC, SPIROC or HARDROC feature large dynamic range, internal digitization (charge and time), auto-trigger and power pulsing that make them suitable for a wide range of applications.
