Papananos, Prof. NTUA
Assistant Professor at the
Microelectronic circuit design group of the NTUA was founded in 1991. The main research area
of the Group is the development of silicon radio-frequency
integrated circuits (RFICs) for telecommunications applications. The Group's researchers
are involved in the design of RF circuits, targetting fully integrated
transceivers for handheld devices. There is also a parallel activity in the
modeling of passive devices for RFICs, while a CAD tool for the simulation of on-chip
inductors is commercially available from MCDG.
Other research areas include VLSI circuits for signal processing, fuzzy logic processors and continuous-time integrated filters. Substantial effort has also been allocated to the modeling of the MOSFET device, with the development of novel MOS structures and transistor models for simulators.
The Group's record holds numerous analogue and mixed analogue-digital chips, in CMOS, Bipolar and BiCMOS technologies.
Main application fields are:
Radio-Frequency Integrated Circuits(RF ICs)
Integrated transceivers for nomadic communications (GSM, GPS, UMTS, Wireless LANs)
continous time filters from very low to high frequencies (video frequencies, RF)
fuzzy logic processing; automatic tuning systems for analog filters
highly linear MOS resistors; evaluation of MOS models for SPICE simulators
(schematic capture, layout, simulation, verification)
Our computers are connected to a local network (Ethernet LAN) which is connected to the NTUA's integrated services network.
Laboratory measurement tools:
The majority of the above devices are connected to a PC (via HP-IB protocol) that runs the Hewlett Packard VEE software, for the visual programming, automation and processing of measurements.
Our measurement setup covers the entire frequency span from DC to 6 GHz. Also, in cooperation with the NTUA's Microwave and Fiber Optics Telecommunications Laboratory it is possible to broaden the range up to 40 GHz.
