System Implications of the Different Powering Distributions for the ATLAS Upgrade Strips Tracker

This paper compares the two novel approaches for the power distribution of the ATLAS Upgrade strips tracker modules, serial and DC-DC powering, from the point of view of a system. Numerous variables have been taken into account, such as total power dissipation and power efficiency, system reliability and protection, noise performances, impact on the material budget of the tracker, and services needs and re-usability
