LAUROC1 : Liquid Argon Upgrade Read Out Chip

Résumé

The analog front-end readout electronics of the ATLAS Liquid Argon (LAr) Calorimeter will be replaced by a single chip for the phase II of the high luminosity Large Hadron Collider at CERN. The cornerstone of the circuit is the preamplifier which is very demanding in terms of low noise (0.4 nV/√Hz), large dynamic range (up to 10 mA, 16 bits) and precise input impedance (25 or 50 Ohms) to terminate the cables from the detector. LAUROC1 ASIC integrates an innovative architecture to fulfil these requirements. Detailed measurements are presented.
