1. 1. Design of Time-to-Digital Converter Circuits for 3D Time-of-Flight Measurements

   Författare :Muhammad Tanveer; Harald Neubauer; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell elektronik; Industrial Electronics;

   Sammanfattning : The three-dimensional view of the world is something that we often take for granted, a phenomenon that has proven challenging for machine vision applications in which description of the environment requires the relative position and motion of different objects in the scene. Currently, range imaging (RIM) measurements are based on digital imaging technology and are merged with the ability to measure the distance to the corresponding object point in each pixel. LÄS MER

   Sammanfattning : The subject of Embedded Measurement Systems (EMS) is the merging of embedded systems and electrical measurement systems. This indicates that EMSs are hardware-software systems dedicated to measuring one or a few physical quantities. LÄS MER

4. 3. Timing Uncertainty in Sigma-Delta Analog-to-Digital Converters

   Författare :Adam Strak; Hannu Tenhunen; Franco Maloberti; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; timing uncertainty; clock jitter; Sigma-Delta Analog-to-Digital Converter; sampling; clock generation; power-supply noise; substrate noise; Electronics; Elektronik;

   Sammanfattning : Denna avhandling presenterar en undersökning av orsakerna och effekterna av timingosäkerhet i Sigma-Delta Analog-Digital-Omvandlare, med speciellt fokus på Sigma-Delta av den switchade kapacitanstypen. Det undersökta området för orsakerna till timingosäkerhet är digital klockgenerering och området för effekterna är sampling. LÄS MER

5. 4. Design of Integrated Building Blocks for the Digital/Analog Interface

   Författare :Niklas Andersson; Mark Vesterbacka; Oscar Gustafsson; Jacob Wikner; Timo Rahkonen; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : The integrated circuit has, since it was invented in the late 1950's, undergone a tremendous development and is today found in virtually all electric equipment. The small feature size and low production cost have made it possible to implement electronics in everyday objects ranging from computers and mobile phones to smart prize tags. LÄS MER
