Thematic Line A
TL A: Micro and Nanoelectronics, Signal Processing and Embedded Systems
Description of the Thematic Line

Thematic Line A (TL A) spans from the level of new components and materials, embedded systems up to the level of signal processing and communications. The mission of this research Line is mainly (but not exclusively) focused on the design low-power SoC (analog, digital and mixed-signal) solutions in advanced CMOS and FPGA technologies oriented for the wireless/wireline communications, consumer-electronics and biomedical industries.

TL A is constituted by 4 research groups: Micro and Nano Electronics Design, Micro Electronics, Materials and Process, Reconfigurable and Embedded Systems, and Signal Processing and Telecommunications. It has 24 Integrated Members, which supervise 31 PhD students.

The main research areas for the groups in Line A are:

1. Micro-nano Electronics Design group:

  • Video and base-band communications circuits,
  • RF circuits;
  • CAD: Analog Circuit Optimizers;
  • Biomedical Circuits;
  • Energy Harvesting.

2. Micro Electronics, Materials and Process Group:

  • Materials and semiconductors (optoelectronics transducers and micro/nano electronics).
  • The main developments were done in semiconductors materials, optoelectronics, micro-electronics and energy conversion.

3. Reconfigurable and Embedded Systems Group:

  • Hardware-software co-design of embedded systems using Petri nets and other models of concurrency (namely hierarchical and concurrent finite state machines based formalisms).
  • Distributed execution of models (using Petri nets and other models of concurrency), emphasis on GALS (Globally-Asynchronous-Locally-Synchronous) and NoCs (Network-on-Chip) paradigms.
  • Reconfigurable computing platforms.

4. Signal Processing and Communications group:

  • Biomedical Signal Processing: EEG, EMG, ECG, and fMRI;
  • Fractional Signal Processing: modeling and applications;
  • Digital Signal Processing: ARMA models and EMD.
  • MAC level concerns: Multipacket reception techniques, performance analysis of access systems.
  • Performance analysis of cognitive radio systems and ad-hoc networks.
  • Routing and traffic engineering in networks, and optimization of the transmitter and receiver for broadband wireless communication.

The multidisciplinary interests of the different group makes possible the development of the devices and materials, connected with embedded systems, using signal processing and communications. This are key aspects of modern ultra-low power, low area and low cost systems used, for example, in modern transceivers applied to Wireless sensor and Actuator Networks.
