  2. 2. 2.1 Academic Awards in Gr.12 • Best student in Physical Sciences • Best student in Engineering Graphics and Design • Fifth overall class position 3 University of Stellenbosch • Final year subjects was in the Telecommunications field • Final year project was in designing logic gates for superconductive elec- tronic circuits • Graduated in 2013 after four years with overall average of 68%, and 88% for final year project. • In July 2015 I went to the University of Yokohama, Japan, to work at the Yoshikawa and Yamanashi Laboratories for 3 weeks. • In July 2015 I attended and presented a poster at the International Su- perconducting Electronics Conference (ISEC) in Nagoya, Japan. 3.1 Fourth year project (Prof C.J. Fourie) With the drive to develop ultra-low power electronics for exascale computing, new methods to reduce power dissipation in superconductive digital circuits were proposed and developed recently. Energy-efficient Single Flux Quantum logic (eSFQ), with zero static power dissipation and 0.8 aJ/bit switch dynamic power dissipation, was demonstrated in 2012. eSFQ clock and bias schemes are more complex than that of traditional SFQ logic families, especially for asynchronous circuits. For this project, redesign the current Stellenbosch University Rapid Single Flux Quantum (RSFQ) logic cell libraries for energy efficiency. These new eSFQ cell libraries will be designed for the Hypres, IPHT and AIST fabrication processes. 3.2 Masters Project (Prof C.J. Fourie) Ambient magnetic fields, trapped flux and fields generated by bias current affect superconducting circuits negatively. Magnetic shielding can be done by shielding volumes with superconducting layers as is done in multi-layer processes such as the AIST advanced process, but holes for vias in such layers make for imperfect shielding. Analysis of current distribution in bias lines and ground return paths give us the ability to predict the behavior of mutual couplings and thus plays an important role in current recycling circuits. We present a specialized magnetic field visualization tool to do so. The tool are written from scratch and in pure C programming language. Magnetic fields are calculated using both FastHenry 2
  3. 3. (rectangular meshing of circuit layers) and TetraHenry (tetrahedral meshing) in conjunction with Biot Savarts law. The tool gives the user a variety of visualization methods for both the magnetic fields and the current distribution, as well as the capability to select or deselect the different layers in a fabrication process to see the effects it has on the overall magnetic field distribution. 4 Part time studies • In my 2nd year I did an online Quantum Mechanic Course from Stanford • In my 4th year (final year undergraduate) I did a Post Graduate Course (Integrated Design 813) under Prof. C.J. Fourie at the University of Stel- lenbosch 5 Vacancy Work In December 2013 and January 2014 I worked at Azotech in the Paarl to re- designed logic gates for the upgraded semiconducting transistor technology. 6 Full Time Jobs In 2014 (1st year MEng) I worked for 6 months at EMSS, Technopark, designing algorithms to improve the GPS tracking of their Android App (HoneyBee). This was to save up money to do my MEng. The contract stated that I would go back to doing MEng full time after 6 months. 7 Hobbies Sport: Played Cricket, Rugby and Soccer in school Played Soccer for four years at University residence, Huis Visser Started Boxing in my MEng course and to date have participated in two tournaments Linux: Gentoo, Arch Linux Gaming: League of Legends, Final Fantasy 3

I have known Mr Van Staden for 2 years now, and found him to be a very diligent student. He is also extremely curious and remarkably attentive to detail. I am Mr Van Staden’s supervisor for his final year undergraduate project on energy- efficient superconductive single flux quantum (eSFQ) logic circuits – a topic which fits squarely into my research activities but which he himself proposed. He approached this project with enthusiasm and resolve more suitable to a Master’s Degree, and has since proved himself to be excellently capable of cutting-edge research. Ruben van Staden would make a useful contribution to South African knowledge and research capacity if he pursues a Master’s Degree, and I would very much like him to continue on this path under my supervision. As such I can help organize an internship for him at an American superconductive integrated circuit design company such as Hypres, Inc., New York, where he can rapidly gain experience in advanced circuit design and the physics of superconductive electronics. Mr Van Staden will be an asset to any high technology engineering company, and I fully support him in any application for work or funding.

  6. 6. ! 11 September 2013 To whom it may concern LETTER OF REFERENCE - R (RUBEN) VAN STADEN Mr Ruben van Staden (Student number: 15998576) is currently registered for the BEng(Electrical & Electronic Engineering)-programme at Stellenbosch University. He is a final year student and will graduate in December 2013. He is a good student and his weighted average over the first 3½ years of undergraduate studies is 67,5%. Ruben approached me towards the end of 2012, at the end of his third year, to discuss his future studies. He expressed a very keen interest in quantum mechanics and was looking for postgraduate opportunities in electronic engineering where he could combine quantum phenomena with electronics. As I am personally working in the research field of superconducting electronic devices, we discussed this technology, with specific emphasis on devices and technologies governed by quantum effects, such as SQUID (Superconducting Quantum Interference Device) magnetometers, and RSFQ (Rapid Single Flux Quantum) integrated circuits. He decided to approach a fellow researcher in the field (Prof CJ Fourie) to act as supervisor for his final year project, an investigation and implementation of energy efficient RSFQ (eSFQ) circuits. Early in 2013 I received a document from Ruben, where he had summarised the underlying theory of superconductivity and also the building blocks (Josephson junctions) and its applications in great detail, clarity and insight. I was complete taken aback, because it was not something that could be expected from third year students. The extent of his understanding of the subject matter was indeed impressive. I have since learnt that he has also done an online course in quantum mechanics from Stanford University and a postgraduate course on integrated circuit design at Stellenbosch University, all in preparation for his postgraduate studies that will commence in 2014, under Prof CJ Fourie's supervision. I have also had the opportunity to engage with Ruben on a non-academic level on numerous occasions. He is as a well-balanced person with good social skills, and also a keen interest in sport, especially soccer and surfing.

  7. 7. I do believe that Ruben has great potential as a researcher. He has already proven that he is extremely inquisitive, and a self-driven person that can operate independently - all required attributes of a good researcher. I am convinced that Ruben will be an asset in any engineering environment and I am excited about his involvement in our research group's activities. I thus strongly support his application for financial assistance for his postgraduate studies. Prof WJ Perold Head: Nanotechnology- and Superconducting Devices Research Group
