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:
- telecomunication systems
Radio-Frequency Integrated Circuits(RF ICs)
Integrated transceivers for nomadic communications (GSM, GPS, UMTS, Wireless LANs)
- signal processing
continous time filters from very low to high frequencies (video frequencies, RF)
- automatic control
fuzzy logic processing; automatic tuning systems for analog filters
- MOS transistor technology
highly linear MOS resistors; evaluation of MOS models for SPICE simulators
Hardware
- 8 Hewlett Packard workstations (B2000, C180, series 700)
- 1 Sun SparcStation 10
- 10 Pentium PCs
Software
- Cadence DFII suite: EDA sofware for integrated circuit development
(schematic capture, layout, simulation, verification)
- ADS: EDA software
- HSPICE (
- Eldo (Anacad): Electronic circuit simulator
- IC - CAP: Device modeling and characterization tool
- FiltorX: Analog filter design software
- Tanner Tools: Simulator and layout tool
- Magic (Berkeley Tools): Layout tool
Our computers are connected to a local network (Ethernet LAN) which is connected to the NTUA's integrated services network.
Laboratory measurement tools:
- probe station from dc to 40 GHz (Karl Suss)
- measurement chamber with temperature and humidity control (Thermotron)
- semiconductor component test system (HP 4061A)
- network analyzers (HP 3589A, HP 54510A)
- spectrum analyzer (HP 8560A)
- noise figure meter (HP 8970B)
- distortion meter (Hameg 8027)
- oscilloscopes (HP)
- signal generators (HP, Hameg)
- logic analyzer (HP 16500A)
- pulse generator (HP 8130A)
- multimeters, power supplies
- RF signal sources (HP 8648B, ESG-D4000A)
- Powermeter (HP EPM-441A)
- Semiconductor Parameter analyzer (Agilent 4155B)
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.
