Ultra-high-field magnetic resonance imaging is a modern medical imaging technology that provides high-resolution insights into brain structure and function, thus contributing to research into neurological diseases and cognitive processes.

With the first European 7-tesla MRI, the STIMULATE research campus and the development of the world's first 14-tesla whole-body magnet the university of Magdeburg is one of the world's leading centers for MRI technology.

In the ERDF project UIC4UHFMRI, Otto von Guericke University Magdeburg (OVGU) is developing an integrated universal console for high-field MRI systems. As part of this interdisciplinary research project, we offer a funded doctoral position with a focus on integrated circuits / chip design. The work takes place in an excellently networked cooperative environment and enables you to develop innovative solutions together with partners from science and industry.

We are looking to strengthen our team and look forward to receiving your application if you already have experience in one or more of the following areas:

• Design of discrete power amplifier circuits for the RF transmit path (RF power amplifier) using GaN, GaO, or InP technology.
• Modeling and verification of power semiconductors during operation in amplifier classes (e.g., Class A, AB, D, etc.).
• Simulation, development, and design of amplifier architectures (e.g., Doherty, envelope tracking, load-modulated balanced, or LINC) with regard to linearity for use in MRI imaging.
• Development and verification of circuit components using EDA tools (e.g., Keysight Advanced Design System or Ansys HFSS).
• Specification of parameters for designing III-V power semiconductors.
• Execute and evaluate circuit simulations (e.g., harmonic balance, PSS, and transient analyses) and electromagnetic field simulations.
• Participation in system design and optimization in the context of integrated RF assemblies.
• Design and heterogeneous integration of modules and circuit boards from discrete ICs and COTS components.
• Metrological verification of systems and assemblies with outputs up to 2 kW peak

The possibility of gaining a scientific qualification as part of a doctorate at the Chair of Integrated Electronic Systems is given (http://elektronik.ovgu.de/).

Your profile:

• At least a good Master's degree in electrical engineering (specializing in circuit technology, high-frequency technology, microelectronics) or comparable disciplines
• Good knowledge in the field of analog circuit technology
• High level of teamwork skills, independent and integrated solution-oriented thinking and the willingness to contribute constructively and purposefully to interdisciplinary project work
• Ability to work independently and autonomously
• German and English language skills (B2/C1)

If you have any questions regarding the advertised position, please contact the project coordinator Christof Pfannenmüller christof.pfannenmueller@ovgu.de or Dr. Marie Horlbeck marie.horlbeck@ovgu.de.

In addition to all the usual social benefits of the public sector, we offer you further advantages, such as the possibility of flexible working hours. We are characterized by modern working conditions, a wide range of training and development opportunities and a good working atmosphere that is highly valued by our employees. We also offer a wide range of sports and leisure activities, extensive catering in our canteens and cafeterias and a company health promotion scheme.

Applications from severely disabled people with equal aptitude, qualifications and professional skills will be given preferential consideration. Otto von Guericke University aims to increase the proportion of women in the academic field and therefore strongly encourages female academics to apply.
