1. 56. Low-Power Multi-GHz Circuit Techniques for On-chip Clocking

   Författare :Martin Hansson; Atila Alvandpour; Per Larsson-Edefors; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CMOS; low-power; high-performance; flip-flop; clocking; leakage-compensation; process-variation; Electronics; Elektronik;

   Sammanfattning : The impressive evolution of modern high-performance microprocessors have resulted in chips with over one billion transistors as well as multi-GHz clock frequencies. As the silicon integrated circuit industry moves further into the nanometer regime, three of the main challenges to overcome in order for continuing CMOS technology scaling are; growing standby power dissipation, increasing variations in process parameters, and increasing power dissipation due to growing clock load and circuit complexity.

3. 57. Ultra-low Power Design Approaches in Memories and Assist Techniques

   Författare :Babak Mohammadi; Integrerade elektroniksystem; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Memory; SRAM; assist technique; charge pump; ULP; ULV;

   Sammanfattning : The need for more functionality and higher performance has increased the number of transistors to billions in current processors. A high number of transistors on the same chip area increases the power density, which in turn heats up the devices and lowers the life time of batteries. LÄS MER

4. 58. Accurate Leakage-Conscious Architecture-Level Power Estimation for SRAM-based Memory Structures

   Författare :Minh Quang Do; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SRAM Power Modeling; Deep Submicron; Power-Performance Estimation Tool; VLSI; Power Estimation; DSP Architecture; CMOS; Cache Power Modeling;

   Sammanfattning : Following Moore’s Law, technology scaling will continue providing integration capacityof billions of transistors for IC industry. As transistors keep shrinking in size, leakagepower dissipation dramatically increases and gradually becomes a first-class design constraint. LÄS MER

5. 59. Low Complexity Techniques for Low Density Parity Check Code Decoders and Parallel Sigma-Delta ADC Structures

   Författare :Anton Blad; Oscar Gustafsson; Zhongfeng Wang; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronics; Elektronik;

   Sammanfattning : Since their rediscovery in 1995, low-density parity-check (LDPC) codes have received wide-spread attention as practical capacity-approaching code candidates. It has been shown that the class of codes can perform arbitrarily close to the channel capacity, and LDPC codes are also used or suggested for a number of important current and future communication standards.

7. 60. Droplet growth in atmospheric turbulence : A direct numerical simulation study

   Författare :Xiang-Yu (李翔宇) Li; Gunilla Svensson; Axel Brandenburg; Wojciech Grabowski; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cloud micro-physics; turbulence; inertial particles; DNS; condensation; collision; coalescence; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

   Sammanfattning : This Ph.D. thesis examines the challenging problem of how turbulence affects the growth of cloud droplets in warm clouds. Droplets grow by either condensation or collision. LÄS MER
