Synthesis and characterization of polyoligosiloxysilicones KU Leuven
Silicon-based materials are of vital importance in today’s society. From the sand and clay dug up from the Earth to be used in construction, to the highly purified forms used in the production of electronics, computers and medical implants, the chemical element Si has found its way into nearly every aspect of our lives. Nevertheless, our highly technological world is fueled by an ever-lasting quest for progress. This search continuously ...
Tracing and Integrated Modelling of Natural and Anthropogenic Effects on Hydrosystems: towards sustainable solutions - TIMOTHY 2 Vrije Universiteit Brussel
The general objective is to develop, validate and apply tools to describe and evaluate the past (1970 for ...
Advance semiconductor wetting and drying: limitations, defect formation and solutions KU Leuven
Semiconductor device fabrication still follows the Moore’s law to increase the process yield by increasing the number of cleaning steps to minimize the number of surface defects. Process induced defect (PID) is a characterization term defined as the main failure mechanism toward efficient cleaning rinsing and drying process. Source of defects might be extrinsic, which represent all contaminations coming from water, ambient and the surface ...
Design of THz Radiators in Nanometer CMOS KU Leuven
In the frequency spectrum, the THz range is located between the millimeter wave and the far field infrared spectrum. There are numerous possible applications in the THz range such as medical/security imaging, spectroscopy, and communication. In these applications, THz signal sources are needed to provide the output signal in a transmitter or provide the LO signal in a heterodyne transceiver. CMOS technologies have the advantage of low cost in ...
Study of the unbound nucleus 7He via 9Be(6He,8Be) transfer reaction KU Leuven
In nuclear physics a continuous effort is made towards the research of new rare isotopes. However, in the exotic-isotope rush, important spectroscopic information on the already-observed exotic nuclei are still missing. The unbound nuclues 7He was firstly identified in the seventies. Since then, a significant number of investigations were performed to study its states. However, an unambiguous information about 7He excited states is still ...
High-Speed, High-Resolution CMOS Analog-to-Digital Converters KU Leuven
The continuous need for higher data rates and low power dissipation for next-generation communication standards calls for innovation in the design of extremely high-speed analog-to-digital converters (ADCs), exceeding 10 GS/s, while maintaining a medium-to-high resolution. Although complex time interleaving ADCs are a partial solution for this demand, the ADC analog front-end remains a speed bottleneck under power constraints. Moreover, even ...
Fully-Integrated Wide Input Range and Two-Quadrant Switched-Capacitor DC-DC Converters KU Leuven
This work focuses on two specific applications of fully-integrated switched-capacitor DC-DC converters, namely wide range operation and two-quadrant operation. For switched-capacitor DC-DC converters to operate efficiently over a wide input or output voltage range, multiple Voltage Conversion Ratios (VCRs) are required, to counteract the losses associated to its output impedance. To achieve wide range operation, this work proposes to use the ...
