2. 1. Control and Design Aspects of Components and Systems in High-Voltage Converters for Industrial Applications

   Author : Per Ranstad; Hans-Peter Nee; Alfred Rufer; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; High-voltage converter; resonant converter; high-voltage transformer; transformer parasitics; IGBT; soft-switching; control; Electric power engineering; Elkraftteknik;

   Abstract : High-frequency dc-dc converters are widely used in power electronic applications, both in consumer products and industrial products. By operating the converter at higher frequencies both a smaller size and better control characteristics can be obtained. READ MORE

4. 2. Design, Processing, and Characterization of High Frequency Flip Chip Interconnects

   Author : Wei-Cheng Wu; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; coaxial; microwave; interconnect; transition; high frequency; microstrip; coplanar waveguide; flip chip; hot-via; packaging;

   Abstract : The demands for high frequency interconnect techniques for microwave integrated circuits (ICs) are growing with increasing operating frequencies of wireless communication systems. Interconnects have significant effect and impact on the overall system performance at high frequencies. READ MORE

5. 3. High Speed Vertical Cavity Surface Emitting Lasers for Short Reach Communication

   Author : Petter Westbergh; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; high speed modulation; GaAs; Semiconductor laser; InGaAs; vertical cavity surface emitting laser VCSEL ; laser dynamics; fabrication;

   Abstract : The vertical cavity surface emitting laser (VCSEL) is a low cost light source with attractive performance characteristics such as low power consumption, high speed capabilities at low currents, and a circular output beam. These features have made the VCSEL an established component in digital communication networks, particularly in short reach optical data transmission applications where links consisting of GaAs-based 850nm VCSELs and multimode fiber have become the standard solution.

6. 4. Modelling and Characterisation of Terahertz Planar Schottky Diodes

   Author : Aik-Yean Tang; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : This thesis deals with the modelling and characterisation of THz planar Schottky diodes, focusing on analyses of geometry-dependent electrical parasitics and the thermal management of the diode chip. Moving towards higher operating frequencies, the diode performance degrades due to high frequency losses, parasitic couplings and self-heating effects. READ MORE

7. 5. High frequency monoloithic integrated circuits for communication systems

   Author : Mehran Mokhtari; KTH; []
   Keywords : ;

   Abstract : The wavelengths of interest in today's communication systemfront-ends are in the same order of magnitude as the availabledevices and circuit sizes. So the wave nature of theinformation can not be neglected. READ MORE
