TDC Integratation in Ring-Oscillator PLLs

Master’s Thesis

For my master’s thesis, I am designing a TDC integrated into a Ring-ocillator PLL for fast, accurate, and PVT stable timing measurements. The circuit will be implemented in a 65 nm CMOS process. Alongside the thesis part I am also working on a conferance paper for the project in collaboration with my supervisors.

The project should cover the full IC design cycle — from architecture and schematic design to layout, verification, tape-out preparation, and post-silicon testing. Including noise and linearity optimization, switchable signal paths, biasing networks, and layout techniques for matching and low-noise performance.

CW Radar

Student project

This was a student project that was presented and demoed at Sensor Decade 2026. The goal of the project was to learn more about radars and be able to develop more advanced radar technology in the future. So far we've developed a functional CW radar and will move on to using the WiFi signal as a source later on.

The eventual goal is to develop a passive radar system using existing WiFi signals as the source signal. By exploiting reflections from WiFi transmissions already present in the environment, the system should perform presence detection and motion tracking without emitting any signals of its own.

Lyra Communication system

Student project

As mentioned above I served as the communtications team leed in Lyra for the GHOST mission. For the project, my team designed a custom 433 MHz transceiver built around the TI CC1200 low‑power RF chip, paired with an AVR microcontroller for configuration, control, and telemetry handling. The PCB shown is our custom transceiver module, which served both as the on‑board transmitter in the satellite and as the ground‑station receiver.

The design required RF layout on PCB level, impedance‑controlled routing, and close collaboration between hardware and firmware teams. The result was a compact 433 MHz communication system made for CubeSat operation and capable of supporting the mission’s full communication link.

ESA CubeSat Summer School

4-week course

I was a student in a 4‑week intensive program featuring hands‑on projects and laboratory sessions led by ESA engineers and university professors. Students from across Europe collaborated throughout the course. The program covered:

• Week 1: Space Systems Engineering and hands-on practice
• Week 2: Model‑Based Systems Engineering
• Week 3: Assembly, Integration, and Testing (AIT) techniques for space systems
• Week 4: Launch and Operations

I have continued working with several participants from the program on a conference paper for International Astronautical Congress (IAC) 2025 and a journal paper in Aerospace Science and Technology.
