The ASIC contains a matrix of hexagonal pixels with 100 μm pitch, readout by low-noise and very fast SiGe HBT frontend electronics. Silicon wafers with 50 μm thick epilayer with a resistivity of 350 Ωcm were used to produce a fully depleted sensor. At the highest frontend power density tested of 2.7 W/cm <sup>2</sup> , the time resolution with the femtosecond laser pulses was found to be 45 ps for signals generated by 1200 electrons, and 3 ps in the case of 11k electrons, which corresponds approximately to 0.4 and 3.5 times the most probable value of the charge generated by a minimum-ionizing particle. The results were compared with testbeam data taken with the same prototype to evaluate the time jitter produced by the fluctuations of the charge collection. </p> Dewey 500.2 34 Département de physique nucléaire et corpusculaire 132 35 Groupe de physique appliquée 135 false Journal of instrumentation 19 04 78761d10-d809-4a48-adda-aeff5afc8e9d Article (Published version) Public Milanesio_2024_J._Inst._19_P040291.pdf 5504610 application/pdf CC BY-4.0 3b775d888b4b3365166b0f21b5fa14fae90184915b8969fc9fab995621b9798e openAccess Faculté des sciences / Section de physique / Département de physique nucléaire et corpusculaire Faculté des sciences / Section de physique / Groupe de physique appliquée
