Géza Kolumbán (Fellow, IEEE)
received his M.S. and Ph.D. degrees from the Technical University
of Budapest in 1976 and 1990, respectively, and his C.Sc. and
D.Sc. degrees from the Hungarian Academy of Sciences in
1990 and 2004, respectively, and his Dr.habil degree from the
Budapest University of Technology and Economics in 2005.
He is an IEEE fellow (2005) with the citation: "for contributions to
double sampled phase-locked loops and noncoherent chaotic
After his graduation, he worked with the Fine Mechanical Enterprise,
Hungary, where he developed local generators, microwave transistor
power amplifiers and VCO circuits for high-capacity microwave
analog radio relay systems. He joined the Research Institute for
Telecommunications, Hungary, in 1980, where he was involved in
many system engineering projects such as SCPC-type
satellite telecommunications system, microwave satellite up- and
down-converters, low-capacity microwave digital radio system, etc.
He headed a group of engineers, whose duty was to develop
frequency synthesizers and local generators for
frequency hopping spread spectrum and satellite systems.
He spent one year with Bilkent University in Turkey (1991-92)
and another year with the Eastern Mediterranean University in
Cyprus (1992-93). He returned to the Budapest University of
Technology and Economics (BUTE) in 1993, where he was a full professor
and the head of Chaotic Systems Team at the Department of
Measurement and Information Systems (MIT) until 2009.
Since then, he is a full professor at The Faculty of Information
Technology (ITK) of Pázmány Péter Catholic University (PPKE) in
As the head of Chaotic Systems Team he has shown that chaos
exists in analog phase-locked loops, elaborated the theory of
chaotic waveform communications and established noncoherent
chaotic communications as a brand new research direction. He
developed DCSK and FM-DCSK, the most popular chaotic
Two of his papers, co-authored with Profs. M.P. Kennedy and
L.O. Chua, have been ranked in
top-cited IEEE Trans. CAS-I articles.
61 of his publications have been cited more than 2000 times.
He has been a visiting professor and researcher to the Electronics Research Laboratory,
UC Berkeley, The Hong Kong Polytechnic University (PolyU), INSA-LATTIS Laboratory, Toulouse, France,
University College Dublin and Cork, Ireland, EPFL, Switzerland, TU Dresden,
Germany and the Hong Kong City University.
In 2012, he established the Laboratory of Software Defined Electronics (SDE) and Virtual Instrumentation (VI)
at the Faculty of Information Technology of Pázmány Péter Catholic University. The SDE-VI Lab has
USRP and PXI-based testbeds, FlexRIO FPGA PXIe setup completed with a baseband transceiver adapter and
many remote controlled instruments from microwave spectrum analyzer to arbitrary waveform generator.
In the SDE-VI Lab any kind of telecommunications systems and test beds can be implemented up to 6.6 GHz
using the SDE approach, and various automated calibration and test beds providing traceability can be built.
In 2012, Prof. Kolumbán was elected as an IEEE Distinguished Lecturer by the Circuits and Systems Society for the time period of 2013-2014. He is offering two lectures in the DLP framework:
Prof. Kolumbán current research and professional interests include software defined electronics,
virtual instrumentation, computer simulation of complex systems, phase-locked loops,
chaotic and UWB radio communications, implementation of
automated manufacturing lines and automated testing systems,
