Institut für CMOS Design

With around 15,000 students and 3,800 employees, the Technische Universität Braunschweig is one of Germany’s leading institutes of technology. It stands for strategic and performance-oriented thinking and acting, relevant research, committed teaching, and the successful transfer of knowledge and technologies to the economy and society. We consistently advocate for family friendliness and equal opportunities.

Our research focuses are mobility, engineering for health, metrology, and city of the future. Strong engineering and natural sciences are our core disciplines. These are closely interconnected with economics, social and educational sciences and humanities.

Our campus is located in the midst of one of the most research-intensive regions in Europe. We work successfully together with over 20 research institutions in our neighborhood as we do with our international partner universities.

The collaboration between the Braunschweig University of Technology, Leibniz University Hannover and PTB, aims at realizing a 50-Qubit quantum computer based on trapped ions. In the frame of this research work, the Institute for CMOS Design is looking for talents worldwide, who want to join our team as

focussing on Analog and Mixed-Signal Integrated Circuits in CMOS**

(EG 13 TV-L)

The position is temporary (3 years) with a possibility of extension. The location is Braunschweig. Remuneration will be in line with the current German collective pay agreement up to TV-L E 13, depending on personal qualification and task assignments.

The control of quantum states of trapped ions is one of the most advances approached on the way towards error tolerant programmable quantum computers. Based on chip technology for ion traps in combination with microwave control, a 50-Qubit-System will be built by the consortium in Lower Saxony. Within this research work the Institute for CMOS Design of the Braunschweig University of Technology has the task to develop integrated circuits in CMOS and BiCMOS technologies at cryogenic temperatures, to enable scalability of qubits.

We are part of an excellent research environment with access to the unique infrastructure of the entire consortium. The team is working in an excellent national and international network and is participating in various large collaborative projects, including „Quantum Valley Lower Saxony“ and the Excellence Cluster „QuantumFrontiers“.

Tasks and assignments:

Active participation in research projects and consortia
Design of analog, mixed-signal and high-frequency integrated circuit for Electronic control of the ion traps, e.g. Direct Digital Synthesizer (DDS), Oscillators, Bit pattern generator, cryogenic DACs and amplitude waveform shaping
Design of highly-integrated low-power and low-noise RF front-ends
RF system-level concept development, level calculations and system modeling
High-level integration of circuits into a System-on-Chip and top-level simulations
Verification in measurement of the circuits on-wafer and on board

Required profile:

Master degree in electrical engineering, physics or relevant field
Knowledge in the field of analog, mixed-signal and/or RF integrated circuits
Understanding in the field of microwave engineering and RF systems
Experience with Cadence Virtuoso is a plus
Experience with electromagnetics field simulation tools is a plus
Good MATLAB skills are advantageous
Expert knowledge in one or more of the above-mentioned research areas
High level of personal motivation, responsibility and continuous learning abilities
Pronounced communication and team building capabilities
Openness to work in a diverse, international working environment
Very good knowledge of the English (and possibly German) language
Readiness to perform research in partner labs at various locations when necessary

Our Benefits:

Work on exciting future-oriented research topics in an inspiring work environment as part of the university community
A vibrant campus life in an international atmosphere with lots of intercultural offers and international cooperations
Pay in accordance with the collective agreement TV-L (a special payment at the end of the year as well as a supplementary benefit in the form of a company pension, comparable to a company pension in the private sector) including 30 days' vacation per year
Advantage portal for employees of TU Braunschweig with attractive offers from strong brand
Flexible working and part-time options and a family-friendly university culture, awarded the "Family-friendly university" audit since 2007
Special continuing education programs for young scientists, a postdoc program, as well as other offerings from the Central Personnel Development Department and sports activities.
