RD53A: A Large Prototype of Pixel Readout Chip for ATLAS and CMS Pixel Upgrades — •Tomasz Hemperek, Hans Krüger, Piotr Rymaszewski, Marco Vogt, Tianyang Wang, and Norbert Wermes — Universität Bonn, Bonn, Germany

The RD53 collaboration was established to develop a new generation of pixel chip for extremely high rates (3GHz/cm2) and very high radiation levels (500Mrad) for ATLAS and CMS phase 2 upgrades. Small-scale demonstrators with 64x64 array of 50x50 um2 pixels containing complex digital architectures have been produced and proven operating at a very small noise and in-time thresholds. A large-scale prototype in 65nm CMOS technology (20mm x 12 mm) called RD53A has been designed and successfully delivered in 2017. RD53A is a complex mixed-signal chip with multiple analog and digital blocks that have been qualified to sustain high levels of radiation. The main concepts of RD53A are described including specification, design and verification process. The plans to develop final pixel chips for the two experiments will be discussed.
