1. 21. CMOS Parallel-Sampling Receivers

   Författare :Henrik Johansson; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : As the processing capacity of the microelectronic circuits increases, the demands on the interconnects will also increase. Hence, there is a need for higher bandwidth to the chips. This dissertation discusses the possibilities to improve the input data rate to CMOS integrated circuits, which is the most common integrated circuit technology today. LÄS MER

3. 22. Implementation of Carrier Phase Recovery Circuits for Optical Communication

   Sammanfattning : Fiber-optic links form a vital part of our increasingly connected world, and as the number of Internet users and the network traffic increases, reducing the power dissipation of these links becomes more important. A considerable part of the total link power is dissipated in the digital signal processing (DSP) subsystems, which show a growing complexity as more advanced modulation formats are introduced.

7. 25. 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.
