Performance of new Amplifier-Shaper-Discriminator chips for the ATLAS high-luminosity upgrade — Sergey Abovyan1, Varuzhan Danielyan1, Markus Fras1, Oliver Kortner1, Hubert Kroha1, Robert Richter1, •Simeon Simeonov1, and Chrysostomos Valderanis2 — 1MPI für Physik, München, Bayern — 2LMU, München, Bayern
The front-end electronics of the ATLAS muon drift-tube chambers will be upgraded in the experiment's phase-II upgrade to comply with the new trigger and read-out scheme at the HL-LHC. A new amplifier shaper discriminator chip was developed in 130 nm Global Foundries technology for this upgrade. A preproduction of 7500 chips was launched in 2019 and tested in 2020. The presentation will summarize the functionality of the new ASD chip, the test set-up and testing procedure as well as the test results which show a production yield of 93%. Based on the successful test of the preproduction chip the serial production of 80,000 chips was carried out in fall 2020.
