The CMS High-Granularity Calorimeter (HGCAL) imposes extremely challenging specifications for the front-end electronics: high dynamic range, low noise, high-precision time information and low power consumption, as well as the need to select and transmit trigger information with a high transverse and longitudinal granularity. HGCROC2 is the second prototype of the readout chip embedding almost all the final functionalities. [...]

HGCROC-Si and HGCROC-SiPM: the front-end readout ASICs for the CMS HGCAL
/ Bombardi, G (CERN) ; Marchioro, A (CERN) ; Vergine, T (CERN) ; Bouyjou, F (IRFU, Saclay) ; Guilloux, F (IRFU, Saclay) ; Callier, S (Ec. Polytech., OMEGA) ; Dulucq, F (Ec. Polytech., OMEGA) ; El Berni, M (Ec. Polytech., OMEGA) ; de La Taille, C (Ec. Polytech., OMEGA) ; Raux, L (Ec. Polytech., OMEGA) et al.
The two variants of HGCROC are the ASICs designed to readout the more than 6 million channels of the future HGCAL of CMS, which will consist of hexagonal silicon sensors for a large part but also SiPM-on-scintillators tiles. The SiPM version of the chip was made from the silicon version by adapting only the first amplifier stage. [...]

Performance study of HGCROC-v2: the front-end electronics for the CMS High Granularity Calorimeter
/ Thienpont, Damien (Ecole Polytechnique) ; de la Taille, C (Ec. Polytech., OMEGA)
/CMS Collaboration
The High Granularity Calorimeter (HGCAL), presently being designed by the Compact Muon Solenoid collaboration (CMS) to replace the existing endcap calorimeters for the High Luminosity phase of the LHC, will feature unprecedented transverse and longitudinal readout and triggering segmentation for both electromagnetic and hadronic sections. The requirements for the front-end electronics are extremely challenging, including high dynamic range (0-10 pC), low noise (~2000 electrons), high-precision timing information in order to mitigate the pileup effect (25 ps binning) and low power consumption (~15 mW/channel).

HGCROC3: the front-end readout ASIC for the CMS High Granularity Calorimeter
/ Dulucq, Frederic (speaker) (OMEGA - Ecole Polytechnique - CNRS/IN2P3)
For the CMS HGCAL, the final version of the 72-channel front-end ASIC (HGCROC3) was submitted in December 2020. HGCROC3 includes low-noise/high-gain preamplifier/shapers, and a 10-bit 40 MHz SAR-ADC, which provides the charge measurement over the linear range of the preamplifier. [...]

This paper presents the design and characterisation of a front-end prototype ASIC for the ATLAS High Granularity Timing Detector, which is planned for the High-Luminosity phase of the LHC. This prototype, called ALTIROC1, consists of a 5$\times$5-pad matrix and contains the analog part of the single-channel readout (preamplifier, discriminator, two TDCs and SRAM). [...]

For the High-Luminosity phase of LHC, the ATLAS experiment is proposing the addition of a High Granularity Timing Detector (HGTD) in the forward region to mitigate the effects of the increased pile-up. The chosen detection technology is Low Gain Avalanche Detector (LGAD) silicon sensors that can provide an excellent timing resolution below 50 ps. [...]
