| Abstract | Abstract: 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 equivalent-noisecharge is 0.6 fC ( 3.38 ke), performing <12-ns preamplifier rise time. These performances have been achieved while managing very high detector parasitic capacitance at the front-end input ( 60 pF). Each channel consumes 10 mA from a single 3.3-V supply voltage. In 0.13-μm CMOS, the total area occupancy is 6.3 mm2. |
