The discovery of a large fab-to-fab variability in the TID response of the CMOS technologies used in the design of ASICs for the particle detectors of the HL-LHC triggered a monitoring effort to verify the consistency of the CMOS production process over time. As of 2014, 22 chips from 3 different fabs in 130nm CMOS technology and 10 chips from 2 different fabs in 65nm CMOS technology have been...
For the high luminosity upgrade to the LHC, the ATLAS inner detector will be replaced by an all-silicon tracker (ITk) consisting of two systems: pixels and strips. The HCCStar and AMACStar are ITk strips ASICs vital for performing the system readout, and monitoring and control.To ensure these ASICs will successfully operate in the high-radiation environment of the HL-LHC, these ASICs need to...
The CERN EP R&D WP 1.2 aims to develop state-of-art monolithic pixel detectors using accessible modern CMOS processes. The TPSCo 65nm process is a suitable candidate and its radiation tolerance and sensor performance are therefore being studied. The impact of the back bias on the transistor behavior has also been measured to provide the designers with accurate models. This process shows...
Single Event Effects (SEE) immunity is one of the major challenges that the RD53 chip is required to meet as being the next generation of the pixel readout chips for the High Luminosity LHC upgrade. Extensive proton and heavy ion beam testing was done to examine the overall chip reliability. The critical analog IP blocks are tested with a Two-Photon Absorption laser and gave an in-depth SET...
The 28nm bulk CMOS technology is a promising candidate as most advanced node for future design in the High Energy Physics (HEP) community. Three ASICs have been designed to evaluate performances and radiation tolerance, both against Single Event Effects and Total Ionizing Dose, of the digital standard cells libraries and foundry SRAMs. This contribution aims at presenting the custom-developed...
