  2. 1. Flip chip for high frequency applications : materials aspects

    Author : Katarina Boustedt; Dag Stranneby; Rao Tummala; Örebro universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flip chip; underfill; bumping; microwave; gallium arsenide; high frequency; thermocompression; soldering; stud bumps; coplanar waveguide; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik; Elektronik; Electronics;

    Abstract : Flip chip has since decades been the primary choice for chip interconnect for high performance circuits. Over the last few years, interest from the microwave arena has increased, and at this point in time microwave flip chip is a possible option for volume production. READ MORE

  4. 2. From Light to Dark : Electrical Phenomena in Cu(In,Ga)Se2 Solar Cells

    Author : Piotr Szaniawski; Marika Edoff; Uwe Zimmermann; Jörgen Olsson; Thomas Walter; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solar cells; Photovoltaics; Cu InGa Se2; CIGS; Electrical characterization; Teknisk fysik med inriktning mot elektronik; Engineering Science with specialization in Electronics;

    Abstract : In Cu(In,Ga)Se2 (CIGS) solar cells the CIGS layer serves as the light absorber, growing naturally p-type. Together with an n-type buffer layer they form a p-n heterojunction. Typically, CdS is used as a buffer, although other, less toxic materials are investigated as alternatives. READ MORE

  5. 3. Low Power and Low Complexity Shift-and-Add Based Computations

    Author : Kenny Johansson; Oscar Gustafsson; Lars Wanhammar; Izzet Kale; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; FIR filters; Function approximation; Digital circuits; Computer arithmetic; Constant multiplication; Addition; Low power; Switching activity estimation; Electronics; Elektronik;

    Abstract : The main issue in this thesis is to minimize the energy consumption per operation for the arithmetic parts of DSP circuits, such as digital filters. More specific, the focus is on single- and multiple-constant multiplications, which are realized using shift-and-add based computations. The possibilities to reduce the complexity, i.e. READ MORE

  6. 4. Multiband LNA Design and RF-Sampling Front-Ends for Flexible Wireless Receivers

    Author : Stefan Andersson; Christer Svensson; Marc Tiebout; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; RF; Microelectronics; Multiband LNAs; RF-Sampling; Sampling Front-Ends; Flexible Wireless Receivers; Multistandard Receivers.; Electronics; Elektronik;

    Abstract : The wireless market is developing very fast today with a steadily increasing number of users all around the world. An increasing number of users and the constant need for higher and higher data rates have led to an increasing number of emerging wireless communication standards. READ MORE

  7. 5. Experiment design with applications in identification for control

    Author : Henrik Jansson; Håkan Hjalmarsson; Paul von den Hof; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; electronics engineering; electrical engineering; Reglerteknik; Automatic control; Reglerteknik;

    Abstract : The main part of this thesis focuses on optimal experiment design for system identification within the prediction error framework. A rather flexible framework for translating optimal experiment design into tractable convex programs is presented. The design variables are the spectral properties of the external excitations.
