1. 11. CMOS Transceiver Front-Ends in Mobile Communication Handsets : Architectures and Building Blocks

   Författare :Ellie Cijvat; Henrik Sjöland; Pietro Andreani; Pieternella Cijvat; Lund University; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; RF CMOS; Wireless Communication; Receiver; Transmitter; Power Amplifier; Harmonic Distortion; Electrical engineering; Elektroteknik; Telecommunication engineering; Telekommunikationsteknik; Electrotechnology; Elektroteknik alt Electrical engineering; RF CMOS; Wireless Communication; Receiver; Transmitter; Power Amplifier; Harmonic Distortion; Electrical engineering; Elektroteknik; Telecommunication engineering; Telekommunikationsteknik;

   Sammanfattning : For mobile communication systems in the low-GHz range, CMOS has increasingly become the technology of choice, and the level of integration in mobile handsets has risen. The use of off-chip components, which increases the handset assembly time and costs, is preferably avoided. LÄS MER

   Sammanfattning : The aim of this study is to describe how Italian advertising for olive oil, pasta and coffee reflects traditions, customs and culturally specific patterns regarding the ways in which these products are used in Italy, and how these culturally specific patterns are interpreted by native readers and non-native readers (Swedish students). The study is based on 22 Italian and 22 Swedish interpretations of three Italian print ads for olive oil, pasta and coffee. LÄS MER

4. 13. Mixers and Multifunctional MMICs for Millimeter-Wave Applications

   Författare :Sten Gunnarsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; G-band; double-balanced Gilbert mixer; sub-harmonically pumped resistive mixer; pHEMT; receiver; image reject mixer; dual-quadrature mixer; balanced resistive mixer; resistive mixer; 220 GHz; high data rate; drain mixer; 53 GHz; single-chip; V-band.; radiometer; mixer; broadband wireless communication; multifunctional; MMIC; GaAs; mHEMT; transmitter; 60 GHz;

   Sammanfattning : This thesis treats the design and characterization of different mixer and multifunctional monolithic microwave integrated circuits (MMICs) in GaAs pHEMT and mHEMT technologies. The MMICs operate at the V (50 – 75 GHz) and G (140 – 220 GHz) bands and several of them demonstrate state-of-the-art performance, level of integration, novel topologies, and/or novel functionality.

5. 14. High speed CMOS optical receiver

   Författare :Håkan Bengtson; Linköpings universitet; []
   Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : Optical communication develops very fast and is today the main method for long distance wired communication. However cost is still high. Looking back to the evolution of optical transmission systems, one main objective of system development has become more and more important; minimize cost per gigabytes per second per kilometre, Gb/s/km.
