A VILNIUS TECH Researcher’s Chip – an Innovation for Transport Electronics

“I wanted to contribute to a future where we can design more crucial electronic solutions here in Lithuania—and perhaps one day manufacture them too,” he says.

By creating this solution, he gained comprehensive competencies covering the entire design process, as well as hands-on experience testing the manufactured chip under real-world conditions. He had to overcome multiple challenges, particularly integrating several complex domains—analog electronics, power electronics and high-voltage technologies.

“The most challenging part was ensuring that the high- and low-voltage circuits inside the chip operate safely and without interfering with each other. The high-voltage parts must withstand up to 60 V, while the low-voltage control logic operates at just a few volts. This required extremely careful design of how these circuits are isolated and how they interact safely,” Šalavėjus explains.

His doctoral supervisor, Prof. Dr. Vaidotas Barzdėnas, Head of the Department of Computer and Communication Technologies at VILNIUS TECH, emphasizes that this achievement is an excellent example of how a unique engineering idea, perseverance and focused work can lead to the realization of even the most complex chip design ambitions.

He notes that no one should fear tackling advanced technological fields—Lithuanian universities are fully prepared to help, train and transfer cutting-edge knowledge and technologies to industry.

“Our infrastructure, partnerships and competencies are strong. The most important step is to boldly move into chip design and high-tech domains. These fields pave the way for solutions in transport, computing, communication systems and other strategic sectors,” says Prof. Barzdėnas.

“Taiwan is truly the world’s chip capital, where the technological ecosystem functions as a single, well-coordinated mechanism. Universities work closely with research institutes and leading chip manufacturers such as TSMC and UMC.

This experience changed my perspective on scientific processes and work culture—seeing how fast and productively projects can be carried out when universities, industry and research centres collaborate inspired me to pursue higher quality, experiment more boldly and think globally,” the young researcher shares.

Still, the biggest difference between Lithuania and Taiwan lies in the scale and specialization of research and production. According to the doctoral student, chip engineering in Taiwan is one of the country’s most important technological fields. For this reason, universities operate many more chip laboratories, each specializing in a specific area—analog electronics, digital logic, high-frequency circuits, power electronics or photonics.

“These specialized laboratories are equipped with advanced tools tailored to their specific fields—from high-voltage testing systems to modern prototyping and measurement stations. This allows ideas to be tested quickly and solutions developed to meet industry standards,” says Šalavėjus.

Taiwan impressed him both professionally and personally—beyond its remarkable chip industry and modern laboratories, he remembers the warm and sincere people, food, exotic climate, beautiful nature and vast cities.

For other young engineers aspiring to work with chip design or pursue internships abroad, Šalavėjus advises: the most important thing is not to be afraid – actively seek opportunities, and when one arises, take it boldly and give it your all.

“You must constantly stay curious, keep learning and look for topics that genuinely excite you. When you find what interests you, you grow naturally,” says the young VILNIUS TECH researcher.
