Abstract For the LS3 ALICE ITS3 upgrade detector material budget reduction has been pushed to limit by proposing a system composed almost exclusively of silicon wafer thinned down 50μm. This improves performance, but adds complexity ASIC design. It requires wafer-scale module with embedded power delivery network and on-chip data transfer, which were usually done through flexible printed circuit cable. contribution covers different aspects design for detector. describes difficulties, shows...

Degradation mechanisms accelerated by harsh conditions (high temperature, electrical stress) can affect circuit performances. Submitted to electromagnetic interferences, aged components become more susceptible, which stirs up questions about the safety level of final application. Unfortunately, impact aging on its susceptibility remains under evaluated and is not taken into account at design level. This paper presents a first attempt modeling methodology aiming predicting interferences....

Abstract The MOSS wafer-scale monolithic sensor, designed for the vertex detector (ITS3) of ALICE experiment, features a pixel input capacitance ∼ 5 fF. Such small is needed to reach satisfactory SNR with low-power analog front-end (36 nW/pixel). This makes design pulsing circuitry characterize performance particularly challenging. As an example, measurements are presented, showing that even parasitic less than aF can significantly alter charge injection from circuit. In this contribution,...

Its performances are compared with other envelope based estimators, including analysis its behaviour regards to measured sample size and signal-to-noise ratio. As an improvement, this does not generate any inconsistent results low values K.
