PhD scholarship in Design Approaches for Terahertz electronics using Active Device Configurations

Danmarks Tekniske Universitet

Lyngby-Taarbæk, 1 stilling

The Department of Electrical Engineering invites applicants for a 3-year PhD position as part of the Marie Sklodowska-Curie Innovative Training Network Programme on Convergence of Electronics and Photonics Technologies for Enabling Terahertz Applications – “CELTA”. The aim of the “CELTA” project is to provide doctoral students with a wide range of skills in both electronics and photonics, necessary to meet future demands for Terahertz systems.

The “CELTA” project consortium consists of 11 partner universities and a high number of associated research institutes and companies.

Responsibilities and tasks
The purpose of the PhD project is to address the challenges related to the signal generation in the 0.1-1 THz frequency range by using innovative transistor-based active circuit approaches. The study should investigate circuit techniques to exhaust the potential for operation near or above the frequency limit (fT and fmax) set by current InP HBT technologies. These circuit techniques must be based on the non-linear characteristics of the InP HBTs and exploit advanced concepts such as Gm-boosting, neutralization, stacking, etc.

The expected outcome of the PhD project will be chip-sets demonstrating highly efficient frequency multiplier chains allowing to extent the frequency range for transistor-based sources sub-harmonically pumped up-conversion mixers for efficient generation of odd harmonics.

The candidate must participate in CELTA training events and should be willing to participate in long term research exchanges to an CELTA associated research institute.


-MSc in electrical engineering or equivalent qualification
-Experience in RF and microwave circuit design
-Knowledge of integrated circuit (IC) techniques
-Basic knowledge of specific simulations software (ADS, HFSS, Cadence etc)
-Excellent command of English (written and spoken) as well as technical writing

Approval and Enrolment
PhD scholarships are subject to academic approval, and the candidates will be enrolled in one of the general PhD programmes at DTU. For information about the general requirements for enrolment and the general planning of the scholarships, please see the DTU PhD Guide.

Please note that due to the Marie Sklodowska-Curie mobility requirements, residents as well as persons who have resided more than 12 months during the last 3 years in Denmark cannot apply for this position. Furthermore, the applicants must have neither a PhD nor research experience = 4 years.

The assessment will be made by Associate Professor Tom K. Johansen.

We offer
We offer an interesting and challenging job in an international environment focusing on education, research, public-sector consultancy and innovation, which contribute to enhancing the economy and improving social welfare. We strive for academic excellence, collegial respect and freedom tempered by responsibility. The Technical University of Denmark (DTU) is a leading technical university in Northern Europe and benchmarks with the best universities in the world.

Salary and appointment terms
Competitive salary to cover living, mobility costs, social and health insurance (according to the Horizon 2020 ITN Marie Sklodowska-Curie Actions Programme regulations) and appointment terms consistent with the current rules for PhD students at DTU.

The period of employment is 3 years.

The candidate will be enrolled as a PhD student at DTU but is required to spend up to 30% of the time at an CELTA associated research institute outside Denmark.
