An Eight-Channels 0.13- $\mu \text{m}$ -CMOS Front End for ATLAS Muon-Drift-Tubes Detectors

An eight-channel readout front end for Large Hadron Collider (LHC) ATLAS muon-drift-tubes detectors is hereby presented (defined 8 × AFE). The system is composed by the cascade of the analog signal processing front end and the Wilkinson A/D, performing both time-over-threshold and charge measurement. The sensitivity at the output of the analog signal processing chain is 14 mV/fC, while the equival...
