The Transition Radiation Tracker, made of 370000 cylindrical straws, is a combined tracking and electron identification detector, which is part of the ATLAS Inner Detector at the CERN LHC. The TRT on-detector electronics is made of 2 types of custom asics, handling the analogue signals from the straws, providing a ternary encoded output (ASDBLR), binning the incoming tracking discriminator sign...
