A monolithic CMOS pixel sensor named OBELIX (Optimized BELle II pIXel) is proposed to equip 5 detection layers upgrading the current vertex detector. Based on the existing TJ-Monopix2, OBELIX is currently designed in 180 nm CMOS process.9 p.application/pdfengcc-by (c) Pham, T.H. et al., 2024http://creativecommons.org/licenses/by/4.0/Circuits electrònicsRadiacióElectrònica digitalElectronic circuitsRadiationDigital electronicsDesign of the OBELIX monolithic CMOS pixel sensor for an upgrade of the Belle II vertex detectorinfo:eu-repo/semantics/article7545552025-05-07info:eu-repo/semantics/openAccess
