Abstract
This paper presents a Fast-Tracker front-end (FTfe) for ATLAS small-diameter Muon Drift Tube (sMDT) detectors of the Phase-II Upgrade HL-LHC. This design addresses the higher rate capability required by sMDT and reduced the dead-time below the maximum drift time, further increasing the efficiency. The front-end ensures a fast baseline restoration with a reset interval of maximum 160 ns, so that the secondary spurious pulses are avoided and the successive muon signals can be detected soon and correctly. The device has been designed in 1V-28nm-CMOS technology; outstanding 4.7mV/fC sensitivity and 0.24fC ENC are achieved with a core area of 0.03 mm2.
