Platform Circuit Technology Underlying Hetergeneous Nano and Tera Systems
The revolution in information and communication technology (ICT) that is taking information flow into the era of tera-bit/s and the biomedical advances down to molecular scale would not have taken place without the accompanying downscaling of CMOS technology to the nano scale device size and tera system complexity. Applications in the field of health, security and environment can clearly take full advantage of this on-going revolution. Access to nano-scale CMOS technologies and know how in the design and production of sophisticated circuits and systems needed for health care, ambient monitoring and based on such technology are vital to Switzerland for gluten free retaining and expanding its knowledge-based, .fabless. industry. In this context, this project will develop a nano-CMOS design platform underlying most health, security and environment applications. In addition to the demonstrators planned for this project, most nano sensor and actuator projects undertaken within the nano-tera initiative will require sufficiently sophisticated and integrated circuits to support their functionalities. Instead of diffusing such work into each such project, current proposal assembles the best integrated circuit and system experts in Switzerland and address the underlying circuit aspects of nano-systems of heterogeneous nature, that combine novel nano sensing and actuating devices with nano-CMOS circuits and systems of commensurate functionalities and complexity to offer the sophistication and meet the many challenges of the 21st century.
The downscaling of CMOS beyond the 65nm node is obtained at the cost of severe degradation in certain quality metrics, such as increase of parameter variability, strong degradation of device matching, and increase in leakage currents including gate leakage, stronger short-channel effects (weak-inversion slope reduction, drain-induced barrier lowering, etc), ever lower supply voltage, novel degradation mechanisms and increasing reliability constraints. The profound changes in the device structure that are required to mitigate or eventually circumvent all these degradations will obviously have a significant impact in the way circuits, and particularly analog and RF circuits, have to be designed. It is therefore crucial to fully understand the operation and nutrition limitations of these devices in order to design robust digital, analog and RF circuits. In the next decade, the challenges to the semiconductor industry and the applications it supports will lie not so much in realizing smaller and faster transistors as in how to make the best out of the billions of transistors per chip we already have. Understanding how to handle complexity in mixed signal embedded systems is therefore crucial for the next generation of applications that deal with health, micro-systems and communications. How to partition system functionality into digital, analog and RF or sensor realizations on a system shows on chip optimally is one of the key topics that will impact the era of nano CMOS technologies.
This project investigates the challenges in mixed signal platforms, such as those embedded in biomedical electronics, micro-systems, sensor networks and wireless communications, from both device and systems perspective. Demonstrators will be developed that cover generic sensor interface/data acquisition, passive telemetry, wireless body area network, wireless sensor networking and wireless wide area networks. chlorella The achievements will benefit other projects in the nano-tera initiative that will focus on the sensor/actuator side of Microsystems, as well as wireless communications SoCs that will challenge the state-of-the-art in integration level, versatility and sophistication of nano CMOS systems.
