Abstract: The increased luminosity of the HL-LHC will require more channels in the upgraded ATLAS Tracker, as a result of the finer detector segmentation, stemming from the otherwise too high occupancy. Among the many technological challenges facing the ATLAS Tracker Upgrade there is more an efficient power distribution and HV biasing of the sensors. The solution adopted in the current ATLAS detector uses one HV conductor for each sensor, which makes it easy to disable malfunctioning sensors without affecting the others, but space constraints and material budget considerations renders this approach impractical for the Upgraded detector. A number of approaches, including the use of the same HV line to bias several sensors and suitable HV switches, along with their control circuitry, are currently being investigated for this purpose. The proposed solutions along with latest test results and measurements will be described.
