   Sammanfattning : Today’s microprocessors with millions of transistors perform high-complexitycomputing at multi-gigahertz clock frequencies. Clock generation and clockdistribution are crucial tasks which determine the overall performance of amicroprocessor. LÄS MER

3. 17. CMOS Analog-to-Digital Converters - Analysis, Modeling, and Design

   Författare :Martin Andersson; Institutionen för elektro- och informationsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : A high-performance and flexible analog-to-digital converter (ADC), that can be integrated in deep-submicron CMOS technology, is a key building block for reduced size, cost and power consumption of digital communication systems. This dissertation concerns the investigation of particular problems associated with the design of such ADCs. LÄS MER

4. 18. Carbothermal synthesis of nano-structured metal, carbides and nitrides, using solution processed precursors; from precursor to product

   Författare :Sarmad Naim Katea; Gunnar Westin; Hilmar Vidarsson; Sanjay Mathur; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Solution-based chemical processing; sol-gel; ceramic powders; transition metal carbides and nitrides; sintering; nickel binder; mechanical properties; Chemistry with specialization in Inorganic Chemistry; Kemi med inriktning mot oorganisk kemi;

   Sammanfattning : This thesis describes how solution chemical based carbothermal syntheses can be used for the synthesis of nanostructured zirconium carbide and nitride nanophase powders as well as a nickel-metal coating on NbC for use as a sintering agent. The focus is on the development of novel synthesis routes using atomic or small nanoscale level mixing of the metal oxide and carbon source in the starting precursors, enabling the use of lower synthesis temperatures and non-agglomerated nanosized powders.

5. 19. Flexible Wireless Receivers: On-Chip Testing Techniques and Design for Testability

   Författare :Rashad Ramzan; Jerzy Dabrowski; Atila Alvandpour; Kari Halonen; Linköpings universitet; []
   Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : In recent years the interest in the design of low cost multistandard mobile devices has gone from technical aspiration to the commercial reality. Usually, the emerging wireless applications prompt the conception of new wireless standards. The end user wants to access voice, data, and streaming media using a single wireless terminal. LÄS MER

7. 20. Nanowire devices for X-ray detection

   Författare :Lert Chayanun; NanoLund: Centre for Nanoscience; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nanowires; Nanowire solar cells; X-ray detectors; X-ray beam induced current;

   Sammanfattning : High spatial resolution X-ray microscopy has become a dedicated tool to study nanocrystals and nanostructure devices in recent years. In general, the spatial resolution of X-ray microscopy depends on the spot size of the X-ray beam and the pixel size of X-ray detectors. LÄS MER
