1. 11. Integrated Transmitters for Cellular User Equipment–Wideband CMOS Power Amplifiers and Antenna Impedance Tuners

   Författare :Jonas Lindstrand; Institutionen för elektro- och informationsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CMOS; LTE; Impedance tuner; Injection lock; Power amplifier; Efficiency; Polar bandwidth expansion; multiband;

   Sammanfattning : The digital cellular systems era started about thirty years ago with the release of the first digital cellphones. These first digital cellphones were very different from today’s slim and esthetic cellular pocket computers. They were not mass-produced in million units a day, and they were designed for radio performance rather than appearance. LÄS MER

3. 12. Micro- and Millimeter Wave CMOS Beamforming Receivers

   Författare :Andreas Axholt; Institutionen för elektro- och informationsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; beamforming; CMOS; front-end; microwave; millimeter wave; phase-locked loop; phased-array;

   Sammanfattning : The available bandwidth in wireless communication systems, such as the 802.11 family, is very limited. Together with the ever increasing data traffic, this causes problems. New possibilities are, however, available thanks to wide license-free bandwidth allocated at higher frequencies. LÄS MER

4. 13. Reactors - Circuit Theory and Silicon Integrated Applications

   Författare :Pietro Andreani; Institutionen för elektro- och informationsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Active Filters; Delay Lines; VCOs; Inductors; Circuit Theory; Capacitors; CMOS; Electronics; Elektronik;

   Sammanfattning : This dissertation deals with reactive components in electric circuits, both as targets for a theoretical circuit analysis, and as devices implemented in silicon processes like CMOS. The frequency behavior of a general electric network is determined by the reactances (i.e. LÄS MER

5. 14. Low Voltage CMOS Radio Receiver Front-End Design
