Internship - Electromagnetic Modelling and Analog/RF Circuit Design for Galvanically Isolated Communication

Objective

The objective of this thesis is to investigate integrated solutions for galvanically isolated communication through a combination of state-of-the-art analysis, electromagnetic modelling, and analog/RF circuit design. The candidate will develop familiarity with FEM-based modelling of the isolation link and may also contribute to the analysis and design of transmitter and receiver circuit blocks.

Thesis Description
The project is structured into three main phases:

- State-of-the-Art Analysis
- Review relevant architectures and physical transmission principles for galvanically isolated communication.

- Compare the main technical approaches and identify key system and circuit-level trade-offs.

- Define suitable evaluation criteria and performance indicators for the selected communication concept.

- Electromagnetic and FEM Modelling
- Become familiar with the FEM-based modelling flow for an integrated galvanic isolation communication link.

- Develop or refine electromagnetic models, including the relevant geometries, materials, excitation ports, and simulation conditions.

- Analyse electrical and RF quantities and assess the impact of selected structural and technology parameters.

- Compare simulation results with available reference or measurement data, where applicable.

- Analog/RF Circuit Design and System Assessment
- Study the interaction between the electromagnetic link and the associated transmitter and receiver circuits.

- Contribute, according to project progress, to the analysis or design of analog/RF transmitter and receiver building blocks.

- Evaluate the overall communication concept and document the methodology, results, and conclusions.

Expected Outcome
The work will provide a structured assessment of integrated galvanically isolated communication solutions, supported by electromagnetic modelling and circuit-level analysis. The expected outcome is a better understanding of the main design trade-offs and a set of modelling and design results that can support the development of future isolated communication concepts.

Candidate Profile
·         Master’s Degree student in Electronic Engineering, Electrical Engineering, Microelectronics, Telecommunications Engineering, or a related field.
·         Good knowledge of analog electronics, circuit theory, and frequency-domain analysis.
·         Basic knowledge of RF concepts and network parameters; familiarity with electromagnetic or FEM simulation is a plus.
·         Interest in integrated circuits, isolated communication, and multidisciplinary modelling and design activities.
