Internship | Automatic Matching Network Layout Synthesis Based On Space Mapping

Impedance matching networks are crucial parts of an (integrated) power amplifier and have a big impact on both the performance and size of the amplifier. For the design of these matching networks on a circuit level, multiple techniques exist which enables the automatic synthesis to a large extend. The optimization of a power amplifier’s matching network, however, is traditionally time-consuming as it requires frequent incorporation of computational expensive electro-magnetic (EM) simulations for accurate layout characterization. Space-mapping is a technique that speeds up the optimization process by using a circuit model for rapid evaluation of the layout structures, with the circuit model being calibrated multiple times during the optimization process using EM-simulations to increase the model’s accuracy. This will enhance the power amplifier’s design cycle significantly.

Developing a space-mapping framework in Keysight ADS for matching network layout synthesis. Activities involved are: investigating suitable circuit models, creation of automatic layout and EM-model generation, implementing and testing different space-mapping/optimization algorithms and applying the framework for matching network design based on electrical and spatial requirements.

The candidate has the qualities to conduct research in a research environment with the help of specialists from the department. Requirements are: Knowledge of RF and preferably optimization, experience with CAD tools (e.g. Keysight ADS) and scripting.

After the first CV selection, the application process will be conducted by the concerning department. TNO will provide a suitable internship agreement. If you have any questions about this vacancy, you can contact the contact person mentioned below.

For this internship vacancy it is required that the AIVD issues a security clearance (VGB) after conducting a security screening. Take into account that this process may take about 8 weeks. If you have been abroad for more than 6 consecutive months, or if you do not have the Dutch nationality, it may take longer. Read more about security screening on the AIVD website.

Important to be aware of before applying:

• Before the start of the internship, the internship agreement from TNO needs to be signed. For students at a college or university based in the Netherlands, TNO uses the UNL-template (supplemented with a number of specific agreements from TNO). For students of foreign and MBO educational institutions, the TNO internship agreement applies. TNO does not sign any other internship agreements.
• Before the start of the internship, the educational institution will need to confirm in writing that:
  • you are enrolled at the educational institution during the internship, and;
  • the internship takes place as part of the programme of the study.
• The confirmation of educational institution takes place by signing the UNL template or forms prepared by TNO.
• Interns at TNO must be in possession of a Dutch residential address at the start of the internship. Performance of internship activities from abroad is not possible.
