Radiation Resilience: Taming the Cosmic Storm with Brain-Inspired Computers: An Exploratory Research to Characterize and Mitigate Radiation Effects in Mixed-Signal Neuromorphic Processors for Space Applications

The number of satellites in orbit is increasing at an accelerating pace. One major issue that currently hinders the range of satellite applications is data analysis. Most data is transmitted back to ground stations for analysis resulting in bandwidth-related issues, or the processing is performed on board, necessitating large computational power...

Blind beamforming techniques for global tracking systems

After the development in the past 120 years since the invention of the first radio transmission, worldwide wireless communication systems are nowadays part of daily life. Behind the shining and astonishing achievement of modern communication systems, the exhaustion of existing frequency spectrum resources has been a concern. In higher frequency...

Level-Crossing ADCs and Their Applications in Biomedical Readout Systems

This thesis describes the theory, design and implementation of levelcrossing ADCs and their system integration. The goal of this work is to explore methods at both the circuit level and the system level to improve the energy efficiency of LC-ADCs and integrate LC-ADCs in biomedical readout systems. Two single-bit capacitive LC-ADCs and an ECG...

Analysis and Design of Decision Feedback Equalizers for Bitrates of 10 Gbps and Beyond in Submicron CMOS

A guideline on how to design and specify a Decision Feedback Equalizer (DFE) for bitrates of 10 Gbps and Beyond. First, this work provides a classification of the state of the art for Decision Feedback Equalizers. Second, this work provides insight about the behaviour of a DFE with increasing number of taps and channel length with measurements...

A Fast and Accurate SystemC / SystemC-AMS Model for Super-Regenerative Radio

A new and precise mixed-signal model for a super-regenerative radio system based on the recent published language SystemC/SystemC-AMS is presented in this thesis. The simulation time of the model is dramatically reduced so that the PLL is able to be included into the model to simulate the frequency difference between the transmitter and receiver...

Active Harmonic Load–Pull With Realistic Wideband Communications Signals

A new wideband open-loop active harmonic load–pull measurement approach is presented. The proposed method is based on wideband data-acquisition and wideband signal-injection of the incident and device generated power waves at the frequencies of interest. The system provides full, user defined, in-band control of the source and load reflection...

A High-Efficiency 100-W GaN Three-Way Doherty Amplifier for Base-Station Applications

A three-way Doherty 100-W GaN base-station power amplifier at 2.14 GHz is presented. Simple, but accurate design equations for the output power combiner of the amplifier are introduced. Mixed-signal techniques are utilized for uncompromised control of the amplifier stages to optimize efficiency, as well as linearity. The combination of the above...
