Chip Development in 65nm CMOS Technology for the High Luminosity Upgrade of the ATLAS Pixel Detector — Leonard Germic1, Miroslav Havránek1,2, Tomasz Hemperek1, Tetsuichi Kishishita1, Hans Krüger1, •Piotr Rymaszewski1, and Norbert Wermes1 — 1University of Bonn, Bonn, Germany — 2Institute of Physics of the Academy of Sciences, Prague, Czech Republic
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. Challenges coming from the higher hit rate will have to be solved by designing faster and more complex circuits, while at the same time keeping in mind very high radiation hardness requirements. Therefore matching the specification set by the high luminosity upgrade requires a large R&D effort. Our group is participating in such a joint development * namely the RD53 collaboration * which goal is to design a new pixel chip using an advanced 65nm CMOS technology. During this presentation motivations and benefits of using this very deep-submicron technology will be shown together with a comparison with older technologies (130nm, 250nm). Most of the talk will be allocated to presenting some of the circuits designed by our group, along with their performance measurement results.
