The Team includes also M.Sc. students from  the postgraduate course curriculum on “Electronics & Communications”.

The main research filed of Analog VLSI Design Team is the design of analog integrated circuits for signal processing. The team is involved with the development of active blocs (e.g opamps, OTAs, CCIIs) which are fully compatible with today market needs in terms of minimum supply voltage requirement and power dissipation. Employing appropriate active elements analog signal processing topologies are designed for baseband and RF applications.

Our research activities could be summarized in the following:

• Design of low-voltage analog integrated circuits:

  • Building blocks (opamps, transconductors, multipliers) for ultra low-voltage power supply (<0.5V).
  • Active elements (current-mirrors, OTAs, CCIIs, CFOAs) for power supply voltage < 1.5V.

   

• Design of continuous and discrete time analog filters:

  • Continuous time linear filters with current-mirrors, CFOAs, CCIIs, etc.
  • Discrete time (switched-capacitor, switched-current) linear filters.
  • Companding filters: Log and square root domain.

   

• Design of integrated RF transceivers for wireless communications:

  • RF frond-end (LNAs, Mixers).
  • Frequency synthesizers (PLL synthesizers, Fractional Synthesizers).
  • Analog low-end.

   

• Design of high speed electronics for optical networks

The team has a remarkable experience on the use of CAD software for VLSI design, such as Cadence, and Tanner Tools software. In addition, the team has access to a fully equipped laboratory for computer-based design, measuring, and characterization of analog and mixed signal systems.

Through its expertise the team has in the past the chance to be in close collaboration with international and Greek companies such as Intel, Intracom, and Theta Microelectronics.

The Electronics Laboratory, where the team belongs, is an associated member of the HSIA (Hellenic Semiconductor Industrial Agency).

The equipment consists of the following :
