Microelectronics Research Group Research

Micrel Lab Research Overview

Research activity at Micrel Lab @ DEIS is organized into different research areas corresponding in groups, each headed by a principal investigator, all of them cooperating with professor Bruno Riccò. These groups combine a wide range of skills, disciplines, and interests, and they collaborate internally and with other universities and research institutes across Europe and USA. Each group has a theme, and researchers have substantial freedom to work together in identifying and pursuing their ideas around these themes with passion and enthusiasm. The activity of the Group, covers a number of issues summarized here after and described in details in each group web sites and pages linked here.

Designers are faced by new challenges due to the complexity of future Multi-Processor Systems-on-Chip (MPSoCs). The design space is very large and many design alternatives need to be explored during architecture definition and tuning. Moreover, gigascale MPSoCs will be increasingly communication - dominated, therefore many efforts are being devoted to the development of aggressively scalable on-chip communication architectures. The research activity in our NoC group addresses both issues. On one hand, we are developing a flexible, functionally-accurate simulation environment for on-chip multi-processors (called MPARM), targeting high accuracy modelling and simulation of such devices. On the other hand, we are developing advanced on-chip interconnects leveraging network technology (generally known as "Networks-on-Chip"). Customized, domain-specific MPSoCs are our primary target and the Xpipes NoC has been designed in our group for this purpose. Overall, we are building an infrastructure allowing us to compare in-house built as well as industrial advanced on-chip interconnects from a performance and power viewpoint, and to accurately analyze the MPSoC design space.

The research activity of AmI (Ambient Intelligence) Group at Bologna University spans multiple aspects of distributed embedded and mobile systems design, with special emphasis on location, user and context aware intelligent media delivery and capture, that enable the so called Ambient Intelligence. Targeted applications concerns navigation in immersive virtual environments, interactive gaming and personalized services for mobile users. The research focus on the design and implementation of the hardware/software infrastructure.

The Bio-research area of Micrel Lab aims at developing Electronic Systems and Data Mining Techniques for genetic analysis and information discovery.
The evolution of micro-fabrication technologies enables the design of small-scale devices (micro-arrays) that can perform a large number of biochemical tests in parallel. These techniques, coupled with high-throughput sensing, signal processing devices, and atomic force microscopy can produce huge amounts of data in a matter of hours. The management of this amount of information determines the increasing development of data mining technologies to automate to some degree, biological and medical information discovery from experiments and publicly accessible databases. In this context, there is a great demand of cheap, portable, and easy to use devices for point-of-care analysis. Micro-fabricated systems with integrated-sensor techniques can satisfy these requirements. These systems integrate on the same substrate the sites of the reaction, the sensors providing electric signals and the circuits for signal conditioning and amplification.

Research Projects Overview

Non-volatile memories

Research supervisor: Massimo Lanzoni

People involved:
Marco Grossi

The research activity in this field focuses on various aspects of non-volatile memories and in particular:
a) Reliability of the cell. This activity aims to study from the physical point of view the reliability issues related to oxide aging in the regions of EEPROM and Flash cells where electron injection takes place. This activity involves both accurate mesurements perfomed on single cells and test patterns, physical modeling of the phenomena and design of special test structures.
b) Multilevel programming. In this field the focus is both on cell behavior during programming and on smart programming schemes for flash memories. The cell programming dynamics is accurately studied analyzing the programming currents. New programming schemees are developed to optimize programming in order to reduce the final cell threshold voltage distribution.
c) Analog appications. In this area non-volatile memories are used as part of circuits for the purpose of tuning of programming the circuit caracteristics.


Solid State Sensors and sensor networks

Research supervisor: Massimo Lanzoni

People involved:
M.gavesi, J. Santoro

a) The activity in the field is focused on the analysis of new sensor technologies. In particular strain sensors realized using amorphous silicon technology are developed and characterized. This research is in collaboration with the University of Rome 1 "La Sapienza".
b) Sensor networks are a recent development of the activity on sensors. The focus is in multisensor system with wireless connection. The aim is to develop a hardware base for the development of AmI technologies.

Virtual instrumentation

Research supervisor: Massimo Lanzoni

People involved:
F. Cibin

Virtual instrumentation have been widely used in all the researches previously mentioned. However particular attenion has been payed to the development of innovative applications in this area. As an example Virtual instrumentation concepts has been exploited to develop a portable audio spectrum analizer on a palm computer platform equipped with Linux OS and acqusition board.
