For the Electrical Engineering (ESAT) TC, Technology Campus Geel, Research group ADVISE we are looking for a PhD student in the field of integrated circuit design.

A flexible SRAM based SEE Radiation Monitor

The Advanced Integrated Sensing lab (ADVISE – http://www.kuleuven.be/advise) is a research group from the Faculty of Engineering Technology of KU Leuven at Technology Campus Geel. ADVISE unites a broad experience in both hardware (design and testing of both PCB and integrated circuit implementations) and software (real-time processing and analysis of large multimodal datasets). This unique combination of expertise enables the development of integrated sensing and communication systems for harsh (radiation) environments or with extremely high reliability requirements. The ADVISE research group has a strong reputation in the field of radiation hardened micro- and nanoelectronic circuit design. The group is also recognized as associate member of the world wide CMS (Complex Muon Solenoid) collaboration with 3500 researchers from all over the world. CMS is one of the largest high energy physics experiments installed on the Large Hadron Collider at CERN and responsible for the discovery of the Higgs boson in 2012.

This Early Stage Researcher (ESR) PhD position is opened for one of fifteen ESRs to be hired in the framework of the Marie Sklodowska Curie Innovation Training Network RADSAGA (http://radsaga.web.cern.ch). During recent years, radiation concerns are gaining attention also in aviation, automotive, medical and other industrial sectors due to the growing ubiquity and complexity of electronic systems and their increased radiation sensitivity owing to technology scaling. This raises the demand for dedicated design and qualification guidelines, as well as associated technical expertise. The training network "RADiation and Reliability Challenges for Electronics used in Space, Aviation, Ground and Accelerators" (RADSAGA) will for the first time bring together industry, universities, laboratories and test-facilities in order to innovate and train young scientists and engineers in all aspects related to electronics exposed to radiation. A total of fifteen ESR PhD project will focus on different aspects of radiation effects in electronics.


The goal of this PhD project is to model, simulate, design and test a controllable SRAM based radiation monitor by modulating the supply voltage during operationand other means of having cell-types with different sensitivities, or SEU cross-sections. The targeted innovation is to develop an SRAM chip in an advanced CMOS technology where the sensitivity to radiation is not minimized by design but made tunable, such that the radiation level (flux) can be monitored.The challenge is to obtain a highly flexible radiation monitor with a controllable SEU cross-section combined with intrinsic tolerance to both total ionizing dose and single-event latch-up. The sensor targets mixed field environments like at CERN and can be used in particle radiation facilities as a beam monitor or as a dedicated instrument for cross-calibration of different facilities. The monitor will also be used by ESR1 and ESR2; while ESR9 and ESR10 will provide predictive tools for SEU/SET and SEL respectively as useful input for the design and assessment of the SRAM modules. It will provide a flexible means of calibrating both test facilities and actual operational environments.


We are looking for a candidate who holds (or will soon receive) a Masterdegree in Electronic Engineering or an equivalent degree. Some experience in orknowledge of CMOS integrated circuit design is required. The candidate shouldhave a strong interest in electronics and nuclear physics.  Finally, good knowledge of English isrequired.

The candidate should have a maximum of four years of full-time researchexperience, including any period of research training, after obtaining the degreewhich formally allowed them to embark on a doctorate in the country in whichthe degree/diploma was obtained or in the host country (irrespective of whetheror not a doctorate was envisaged).

ESRs cannot be PhD holders at the start of their employment contract.

The European Commission's mobility rules state : At the time ofrecruitment by the host organisation, researchers must not have resided orcarried out their main activity (work, studies, etc.) in the country of theirhost organisation for more than 12 months in the 3 years immediately prior tothe reference date. Short stays such as holidays and/or compulsory nationalservice are not taken into account. In case above requirement prevents you fromapplying for a KU Leuven position, please look at the related positions at ourRADSAGA partner institutes.

Proficiency in English is required; training in other languages can beprovided through the ITN's training budget.


The duration of the PhD project is 4 years, starting between July and October, 2017.
