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.},
