16. Microwave Frequency Stability and Spin Wave Mode Structure in Nano-Contact Spin Torque Oscillators
Sammanfattning : The nano-contact spin torque oscillator (NC-STO) is an emerging device for highly tunable microwave frequency generation in the range from 0.1 GHz to above 65 GHz with an on-chip footprint on the scale of a few μm. LÄS MER
17. On PLL Modeling and Design in Nanometer‐Scale CMOS
Sammanfattning : Integrated circuits play a vital role in our everyday lives, from wireless gadgets and multimedia players to sensors and processors that control vital infrastructure. Since most electronic circuits need a clean, stable clock or carrier to function, one of the most important components of integrated circuits is the phase-locked loop. LÄS MER
18. Spin Torque Oscillator Modeling, CMOS Design and STO-CMOS Integration
Sammanfattning : Spin torque oscillators (STOs) are microwave oscillators with an attractive blend of features, including a more-than-octave tunability, GHz operating frequencies, nanoscale size, nanosecond switching speed and full compatibility with CMOS technology. Over the past decade, STOs' physical phenomena have been explored to a greater extent, their performance has been further improved, and STOs have already shown great potential for a wide range of applications, from microwave sources and detectors to neuromorphic computing.

19. Advanced Schottky Diode Receiver Front-Ends for Terahertz Applications
Sammanfattning : This thesis treats the development of high frequency circuits for increased functionality of terahertz receiver front-ends based on room temperature Schottky diode technology. This includes the study of novel circuit integration schemes, packaging concepts as well as new measurement and characterisation techniques. LÄS MER
20. Multiuser Serially Concatenated Continuous Phase Modulation
Sammanfattning : A multiuser communication system using serially concatenated and randomly interleaved continuous phase modulation (SCCPM) over the additive white Gaussian noise (AWGN) channel is investigated. The users, which may be asynchronous, are allowed to have individual energy levels as well as carrier frequencies and phases. LÄS MER
