Presentation title :
Technology Scaling and Low-Power Analog Design

Presentation abstract : Modern and future ultra-deep-submicron technologies make challenging the analog design especially when supply voltage, power consumption, and resolution must match digital counterparts.
The decrease of the supply voltage reduces the voltage headroom in analog circuits, the gate leakage current increases, the voltage gain decreases in planar bulk MOS transistors, 1/f noise deteriorate when using new high-k gate dielectrics. The consequences of the above limits are twofold: to remain a little behind the technology front and to push the analog digital interface toward the digital domain. However, a global digital world is impossible because signals of the real world are analog. Therefore, the trend is to focus on the interfaces: A/D and D/A, and minimize the analog pre-processing. Nevertheless, for achieving a suitable resolution it is necessary to design op-amps or OTA with an acceptable gain, and to obtain comparators with good sensitivity and low offset, thus facing in addition to the above the problem of correcting or compensating for the transistor and passive components mismatches.
Technologists alleviate only some of the mentioned problems, as they must optimize analog and digital features; instead, it is often necessary to invent new circuit topologies and design techniques. An additional challenge comes for portable and nomadic applications that require very low power consumption while maintaining acceptable resolution and linearity: the mobility request involves performing complex functions with a limited power refueling. Moreover, in case of autonomous operation no power is specifically provided and the system must have the capability to acquire the power that needs and modulate its activity depending on the available power budget.
After briefly reviewing suitable processing and data-converter algorithms the presentation discusses in some detail design method and various tricks for optimizing the power effectiveness. The above design directions determined many research results, mainly in the data converter field, with silicon implementation that are briefly examined and discussed.



Presentation title :
Research in Microelectronic: fun or innovation boost?

The recent use of knowledge for generating economical and social advantages is changing the paradigm of research activity, especially in the microelectronic field. Since the results of research have a direct impact on high-tech products it is necessary to change the approach and the researchers attitude. Before the activity was aimed at satisfying the intellectual curiosity but now there is an increasing push from the market. However, the short-term activities can be perilous and contrasted by scientists that commit a rigorous cultural independence and become skeptic on the real importance of industrial links. The key is to find the right balance between basic  and applied activity and to find the right strategy for inspiring activity that is good for progress . This talk discusses the recent shift in the microelectronic research and presents some possible approaches to favor the right personal attitude and national strategies that properly face the new scenario.
