Master’s Thesis: Behavioral Modeling of a Digital-to-Analog Converter for Qubit Control

The Central Institute of Engineering, Electronics and Analytics – Electronic Systems (ZEA-2) is a scientific and technical institute of the Forschungszentrum Jülich GmbH, which performs research and development projects in cooperation with the institutes of the Forschungszentrum and external partners. The focus of the work is the development of electronic and information technology system solutions in sensor technology and detector technology, signal and data processing, measurement technology as well as imaging and processing.


Building a quantum computer needs integration of more and more quantum bits, called qubits, on one chip. As a result the needed amount of wiring and lab equipment is increasing sharply. At the same time the connection to the qubits is very limited since they are placed inside a dilution refrigerator at cryogenic temperatures. Overcoming this challenge can be only done by an integrated electrical control and read-out solution.

Your Task:
The aim of this thesis is to develop a behavioral model of a Digital-to-Analog Converter (DAC) under consideration of nonlinear effects.

The first step is to build a 1st order behavioral model of a DAC to fit into the bigger modelling framework of the complete control electronics. In the second part then nonlinear effects for a specific DAC topology (e.g. charge-based DAC) should be included in the model and verified in the framework.

Your profile:

  • Electrical engineering, physics or computer science background
  • Experience with a hardware description language and Matlab/Simulink
  • Good German or English speaking and writing capabilities
  • High personal motivation
  • Team spirit

We Offer:

  • A cutting edge topic in engineering science
  • The opportunity to work together in a team of highly motivated scientists and engineers
  • Further development of your personal abilities in connection within a socially balanced work environment

We will be glad to assist you in your initial personalized training.

The Forschungszentrum Jülich GmbH would like to increase the number of employees in this area. We are therefore particularly interested in female applicants. Applications made by disabled people are particularly welcome.
