Development of an analog front-end in a 65 nm CMOS mixed-signal chip for readout of high granularity silicon pixel sensors for particle tracking in the innermost layers of ATLAS and CMS at HL-LHC: the international RD53 collaboration and the INFN CHIPIX65 group Demanding specifications for noise, threshold dispersion, minimum threshold, power dissipation, area, tolerance to extremely high levels of ionizing radiation,... Motivation This front-end was integrated in single channel prototypes, in
