  1. 88. A complete DCDC converter ASIC for LHC upgrades
    Stefano Michelis (CERN)
    20/09/2012, 14:50
    Oral
    A new and complete DCDC converter ASIC prototype has been designed and manufactured in a commercial 0.35um CMOS technology. The circuit is aimed at applications in LHC upgrades, where it can function in the intense magnetic field and survive to the radiation environment of even the trackers. Rated for an input voltage up to 10V, it provides a selectable output voltage and embeds under-voltage,...

  2. 89. Design of a New Front-End Switching Power Supply
    Gary Drake (Argonne National Laboratory)
    20/09/2012, 15:15
    Oral
    We present the design of an upgraded switching power supply for the front-end electronics of the ATLAS Hadron Tile Calorimeter. The new design features significant improvement in noise, improved fault detection, and improved reliability, while retaining the compact size, water-cooling, output control, and monitoring features. We discuss the steps taken to improve the design. We present the...

  3. 119. A DC-DC conversion powering scheme for the CMS pixel detector upgrade
    Katja Klein (Rheinisch-Westfaelische Tech. Hoch. (DE))
    20/09/2012, 15:40
    Oral
    CMS has adapted a DC-DC conversion powering scheme for its phase-1 pixel upgrade, to be able to deliver the required amount of power with the existing cable plant. The presentation will focus on aspects that are relevant for the integration of DC-DC buck converters into a detector system. New measurements based on a full-scale prototype ASIC (AMIS4, CERN PH-ESE) will be presented,...

  4. 31. Simulations and Measurements for a Concept of Powering CALICE-AHCAL at a Train-cycled Accelerator
    Peter Goettlicher (Deutsches Elektronen-Synchrotron (DE))
    20/09/2012, 16:05
    Oral
    To build homogeneous high granularity calorimeters low power consumption per channel is essential. Linear e+e- collider design duty cycles foresee bunch delivery over short periods, 1ms, followed by long, 200ms, breaks. Power cycling frontend electronics can reduce power consumption by a factor 100. For a full scale CALICE-AHCAL switched currents reach kilo Amperes magnitudes. This talk...
