Query: Prototype Active Silicon Sensor in 150 nm HR-CMOS Technology for ATLAS
  Inner Detector Upgrade   The LHC Phase-II upgrade will lead to a significant increase in luminosity,
which in turn will bring new challenges for the operation of inner tracking
detectors. A possible solution is to use active silicon sensors, taking
advantage of commercial CMOS technologies. Currently ATLAS R&D programme is
qualifying a few commercial technologies in terms of suitability for this task.
In this paper a prototype designed in one of them (LFoundry 150 nm process)
will be discussed. The chip architecture will be described, including different
pixel types incorporated into the design, followed by simulation and
measurement results.
