In view of the High Luminosity upgrade CERN LHC, forward CMS Muon spectrometer will be extended with two new stations improved Resistive Plate Chambers (iRPC) covering pseudorapidity range from 1.8 to 2.4. Compared present RPC system, gap thickness is reduced lower avalanche charge, and an innovative 2D strip readout geometry proposed. These improvements allow iRPC detector cope higher background rates. A Front-End-Board (FEB) designed signals a threshold as low 30 fC integrated Time Digital...
