Characterization and verification of the Shunt-LDO regulator and its protection circuits for serial powering of the ATLAS and CMS pixel detectors
/ Kampkötter, Jeremias (Applied Sci. U., Dortmund) ; Karagounis, Michael (Applied Sci. U., Dortmund) ; Koukola, Dominik (CERN) ; Loddo, Flavio (INFN, Bari) ; Orfanelli, Stella (CERN) ; Luengo, Alvaro Pradas (EADS CASA, Madrid) ; Traversi, Gianluca (Bergamo U.) ; Kokozinski, Rainer (Duisburg-Essen U.)
The Shunt-LDO regulator has been integrated in the ATLAS and the CMS pixel detector RD53 front-end chip to implement the serial powering scheme which both experiments have chosen as the baseline option for the HL-LHC upgrade. The performance of the integrated regulators has been characterized and specific design challenges have been identified which are related to layout parasitics and shallow trench isolation (STI) stress effects.

Stabilization and Protection of the Shunt-LDO regulator for the HL-LHC pixel detector upgrades
/ Kampkoetter, Jeremias (Applied Sci. U., Dortmund) ; Karagounis, Michael (Applied Sci. U., Dortmund) ; Stiller, Andreas (Applied Sci. U., Dortmund) ; Traversi, Gianluca (Bergamo U.) ; Luengo, Alvaro Pradas (Zaragoza, ITA) ; Koukola, Dominik (CERN) ; Orfanelli, Stella (CERN) ; Hinterkeuser, Florian (Bonn U.)
Serial powering is the baseline option for the pixel detectors in both the ATLAS and the CMS experiments targeting the phase II HL-LHC upgrade. The Shunt-LDO regulator is integrated in the front-end chips to generate the required supply voltages. [...]

System level serial powering studies of RD53A chip
/ Pradas Luengo, Alvaro (Zaragoza, ITA) ; Koukola, Dominik (CERN) ; Orfanelli, Stella (CERN) ; Christiansen, Jorgen (CERN) ; Karagounis, Michael (Fachhochschule Dusseldorf) ; Arteche, Fernando (Zaragoza, ITA)
Serial powering is the baseline choice for low mass power distribution for the CMS and ATLAS HL-LHC pixel detectors. The RD53A prototype chip (65 nm CMOS) integrates 2 shunt-LDO (SLDO) regulators that allow providing constant voltage to each power domain (analog and digital) within a serial power chain with constant current.

/RD53
RD53A is a large scale 65 nm CMOS pixel demonstrator chip that has been developed by the RD53 collaboration for very high rate (3 GHz/cm$^2$) and very high radiation levels (500 Mrad, possibly 1 Grad) for ATLAS and CMS phase 2 upgrades. It features serial powering operation and design variations in the analog and digital pixel matrix for different testing purposes. [...]
