Pixel Readout Chip for ATLAS HL-LHC Hybrid Pixels in 65nm CMOS Technology — Tomasz Hemperek, Tetsuichi Kishishita, Hans Krüger, •Piotr Rymaszewski, Marco Vogt, Tianyang Wang, and Norbert Wermes — University of Bonn, Bonn, Germany

The LHC High Luminosity upgrade will result in a significant change of environment in which particle detectors are going to operate, especially for devices very close to the interaction point like pixel detector electronics. Due to similar requirements in terms of pixel size (50µm × 50µm), hit rate (3 GHz/cm²), and radiation tolerance (500Mrad) ATLAS and CMS are developing together a pixel readout chip in 65nm CMOS technology to cope with this challenge. This collaboration, named RD53, started in 2013 and is now close to submitting a first large scale prototype. In this talk the chip overview will be presented, which includes the design flow, read-out concept and the development of specialized IP blocks. Issues arising from the very high radiation tolerance requirement will be discussed. A large focus will be given to the parts designed by our group.
