/ Klekotko, A (Leuven U. ; CERN) ; Baszczyk, M (CERN) ; Biereigel, S (CERN) ; Kulis, S (CERN) ; Martina, F (CERN) ; Moreira, P (CERN) ; Tavernier, F (Leuven U.) ; Prinzie, J (Leuven U.)
Ongoing developments in the field of radiation-toleranthigh-speed transmitters (HSTs)aim at increasing thedata rates above 25 Gb/s while increasingtotal ionizing dose (TID)tolerance above 1 Grad. The use of half-ratearchitectures imposes tight constraints on clock signal quality, in particular itsduty-cycle. [...]

Low-noise and low-power front-end in 130 nm CMOS for triple-GEM detectors supporting wide range of detector capacitances with gain and peaking time programmability.
/ Dabrowski, M (CERN) ; Aspell, P (CERN) ; Bravo, C (UCLA, Los Angeles (main)) ; De Lentdecker, G (U. Brussels (main)) ; De Robertis, G (INFN, Bari) ; Irshad, A (CERN ; Unlisted, PK) ; Licciulli, F (INFN, Bari) ; Loddo, F (INFN, Bari) ; Petrow, H (Lappeenranta U. Tech.) ; Rosa, J (U. Brussels (main)) et al.
An analog front-end in 130 (nm) CMOS technology was developed for the readout of triple-GEM detectors in the CMS experiment at CERN. The front-end has programmable peaking time - 15, 25, 35 and 45 (ns) - and gain - 48, 16.4 and 8.6 (mV/fC) - and is able to support a detector capacitance ranging from 0 to 120 (pF). [...]

Sci. Res. Tech.) ; Asghar, I (NCP, Islamabad) ; Aspell, P (CERN) ; Assran, Y (Cairo, Acad. Sci. Res. Tech.) et al.
The CMS Collaboration has been developing large-area triple-gas electron multiplier (GEM) detectors to be installed in the muon Endcap regions of the CMS experiment in 2019 to maintain forward muon trigger and tracking performance at the High-Luminosity upgrade of the Large Hadron Collider (LHC); 10 preproduction detectors were built at CERN to commission the first assembly line and the quality controls (QCs). These were installed in the CMS detector in early 2017 and participated in the 2017 LHC run. [...]

The eCDR-PLL, a radiation-tolerant ASIC for clock and data recovery and deterministic phase clock synthesis
/ Leitao, P (CERN) ; Francisco, R (CERN) ; Llopart, X (CERN) ; Tavernier, F (Leuven U.) ; Baron, S (CERN) ; Bonacini, S (CERN) ; Moreira, P (CERN)
A radiation-tolerant CDR/PLL ASIC has been developed for the upcoming LHC upgrades, featuring clock Frequency Multiplication (FM) and Clock and Data Recovery (CDR), showing deterministic phase and low jitter. Two FM modes have been implemented: either generating 40, 60, 120 and 240 MHz clock outputs for GBT-FPGA applications or providing 40, 80, 160 and 320 MHz clocks for TTC and e-link applications.
