Radiation hardened high-speed ADC for imec’s next generation DARE platform KU Leuven
Radiation hardened integrated circuits are a necessity for applications in space, high-energy physics and nuclear facilities where ionizing radiation causes total dose degradation of the integrated devices as well as reversible and irreversible single-event effects from high-energy particles. The aim of this PhD project is to develop novel radiation-hardening-by-design techniques on system architecture, circuit, and layout level. Their ...
Radiation hardened high-speed digital circuits with multi-cell upset mitigation techniques for reliable communication links in nanoscale technologies KU Leuven
In this research project, innovative circuit techniques will be developed to enable low power, extremely high-speed radiation hardened digital communication links. Such communication channels are required in complex nuclear facilities such as the Large Hadron Collider, nuclear fusion power plants and high-performance satellites. Generally, digital chips become faster each year with smaller transistors, but they also become more sensitive to ...
Radiation Hardened Aging Resilient Digital Integrated Circuits in Nanoscale CMOS Technology KU Leuven
long-term reliability of recent CMOS technologies is impacted by different intrinsic degradation mechanisms that progressively alter their electrical characteristics (BTI, HCI, TDDB...). Due to the ongoing aggressive scaling process, those mechanisms exhibit significant dispersions related to the process details and variability. The parametric evolution induced by those mechanisms constitutes a reliability risk, both directly, by compromising ...

Integrated Time-based Signal Processing Circuits for Harsh Radiation Environments KU Leuven
This research focuses predominantly on the design and implementation of new architectures for integrated data converters based on time-based signal processing for applications requiring high levels of reliability in harsh radiation environments. The radiation-hardened integrated circuits (ICs) were designed with high radiation tolerance in mind, making them ideal for high energy physics (HEP) experiments, vital long-term space missions, and ...
Radiation tolerant CMOS optical and wireline communication circuits KU Leuven
The next generation of integrated systems on chips (SoCs) for space applications demand a large scale of integration, combined with ever increasing susceptibility to single-event effects in nanoscale CMOS technologies such as 65 nm and 28 nm nodes and 22 nm FDSOI nodes. Many of these SoCs require the generation of clocks, frequencies or an exchange of serial data in the chip. In clock- or frequency synthesizers, a PLL is used to generate a ...
Design of radiation tolerant timing systems with sub-picosecond accuracy. KU Leuven
The goal of this research was to develop and test integrated CMOS circuits for radiation tolerant time-based circuits with picosecond accuracy for nuclear applications and high-energy physics. The main applications for which these circuits were developed, are time-based readout interfaces in high-energy physics particle detectors, clock generation and data-transmission for these detectors. During this research, a radiation tolerant ...
