6. Microwave and Millimeter-Wave Monolithic Integrated Circuits in CMOS and GaAs-mHEMT Technologies
Sammanfattning : The objective of this work has been to design and characterize microwave and millimeter-wave components and circuits within a 90 nm Si-CMOS process and a 100 nm GaAs-mHEMT process. The work is divided in two parts depending on the technology. LÄS MER
7. EM Design for New Ultra Wide Band Technologies: Eleven Feed Baluns, Bowtie Antennas and Gap Waveguides
Sammanfattning : UWB (ultra wideband), depending on the application requirement, is usually referred to more than 500 MHz bandwidth for radio/wireless applications. Here in this thesis it is also used to denote extremely wideband antennas and components of several octaves bandwidth, particularly for high frequency applications. LÄS MER

9. ASIC Implementation of a Delayless Acoustic Echo Canceller: Architecture and Arithmetic
Sammanfattning : Application specific digital signal processors are superior compared to standard digital signal processors in a number of application fields, mainly due to high throughput and low power consumption traded for flexibility. This thesis deals with two areas related to hardware implementation of custom digital signal processors: design methodology and efficient implementation of arithmetic circuits. LÄS MER
10. Novel RF MEMS Devices for W-Band Beam-Steering Front-Ends
Sammanfattning : This thesis presents novel millimeter-wave microelectromechanical-systems (MEMS) components for W-band reconfigurable beam-steering front-ends. The proposed MEMS components are novel monocrystalline-silicon dielectric-block phase shifters, and substrate-integrated three-dimensional (3D) micromachined helical antennas designed for the nominal frequency of 75 GHz.
