Personal profile

Quote

"As  long  as society  relies  on  digital electronics, technologies for analog-to-digital conversion and vice versa are unavoidably necessary – in particular in the communication domain, where society will always need higher speeds for lower costs."

Research profile

Georgi Radulov is an assistant professor in High-Speed High-Performance Data Converters with the Mixed Signal Microelectronics research group at the TU/e department of Electrical Engineering. His research aims at understanding, improving, and expanding the knowledge and techniques for high-frequency high-performance data converters. In particular, his research focuses on RF and mm-wave Transmitters and Receivers; Phased arrays; Nyquist and Sigma-Delta Data converters; and Built-In-Self-Testing.

Georgi Radulov holds 3 US patents. In 2008, he was awarded the Outstanding Student Paper of the IEEE conference APCCAS 2008, in Macau. Georgi Radulov has more than 30 publications. He has successfully supervised 1 PhD student (promoted with Cum Laude honors) and more than 15 final projects of Master and Bachelor students.

Academic background

Georgi Radulov received his MSc degree in Electrical Engineering in 2001 from the Technical University of Sofia (Bulgaria). Since August 2001, he is member of the Mixed-Signal Microelectronics (MsM) Group at Eindhoven University of Technology (TU/e, the Netherlands). In 2004, he received a Professional Doctorate in Engineering (PDEng) from the Stan Ackermans Institute at TU/e, and in 2010, he obtained his PhD with his thesis 'Flexible and self-calibrating current-steering digital-to-analog converters: analysis, classification and design'. Since 2009, he is an Assistant Professor at the MsM Group. From 2008 to 2012, Georgi Radulov was a director of Welikan B.V. which provided consultancy services in the area of analog and mixed-signal IC research. Since 2012, Georgi Radulov is teaching courses in the following subjects: Semiconductor devices and materials; Analog and Mixed-signal CMOS design; Basic CMOS Analog Circuits; Data Converters.
