Development of an octal CMOS ASD for the ATLAS Muon detector
Le résumé fourni par la source
Development of a CMOS amplifier/shaper/ discriminator for the ATLAS Muon detector is presented.The first phase of this work has resulted in a simplified 4-channel device (ASD-lite) fabricated in HP 0.5µm n-well CMOS operating at 3.3 volts.Highly accurate DC models resulted in performance which closely matches SPICE predictions.On-chip crosstalk, a parameter not easily simulated, is measured to be below 0.5%.Results of chip measurements and on-chamber tests will be presented.This device will be used for early testing of ATLAS MDT (Monitored Drift Tube) modules.Further work on the final octal MDT-ASD, which will be fully programmable and include Wilkinson leading edge charge measurement, will be presented.
