Lecture: Microelectronic Systems for Improved Quality of Life
Microelectronic revolutions come in waves that are driven by necessity. Currently, the aging population is creating a need for various kinds of electronic systems to improve their quality of life. These include the restoration of lost functionality via electronic implants, better health screening technology and non-invasive monitoring in the home environment. In this talk I will present work that has been done towards addressing these needs, whether it be through the development of new required building blocks or through the development of more complex systems that combine custom built hardware and software. In particular the talk covers work done towards developing a vestibular implant for balance restoration, a single chip low-power imager for a bionic eye, a cancer screening capsule for detecting early-stage carcinomas in the small intestine and a bio-inspired acoustic scene analysis system.

Lecture: Improving Ultra Low Energy Digital Circuits and their DC/DC Converters
Scaling has reduced the maximum supply voltage of the current generations of integrated circuits down to below the voltage supplied by all kind of batteries. Low energy digital circuits apply even lower voltages, operating in the near or sub-threshold regions. Furthermore, the supply voltage is adjusted on real time according to the processing load and current SoCs apply several voltage domains. This talk presents on-going research activities at the Microelectronics Group of Universidad de la Republica on these fields. On one hand, the basis of ultra low energy, sub-threshold digital circuits are presented. Then it is shown how circuit and device modeling lead to techniques for significant energy reduction. Results are evaluated in a 28nm FD-SOI process. On the other hand, a novel approach, based on charge recycling, for improving efficiency of integrated DC/DC converters used for powering these ultra low energy blocks is discussed. Its application, including validation in experimental prototipes in 130nm Bulk CMOS, will be shown in a novel modular architecture suitable for a wide output voltage range.

Lecture: Wireless power transmission for sustainable electronics (WIPE): main contributions from the European Coperation in Sciences and Technologies (COST) action IC1301.

Wireless Power Transmission (WPT) focus mainly the efficient design for circuits, systems and strategies specially tailored for battery-less systems, battery-free sensors, passive RFID, Near Field Communications (NFC). WIPE is nothing but a set of enabling technologies aimed to foster the internet of things (IoT). Main applications of WIPE techniques are found in different areas such as: Healthcare, Security, Agriculture, Vehicular Industry, Sports and Gaming, Aerospace Industry, Flexible Manufacturing Industry, Structural Health Monitoring.

The European COST action IC1301 (http://www.cost-ic1301.org) brings together RF and mixed-signal circuit and system designers as well as material sciences engineers, from academia and industry and with different backgrounds to:

  1. Provide enhanced circuit and subsystem solutions to increase the efficiency in WPT;
  2. Investigate the use of novel materials and technologies that allow minimizing cost and maximizing integration of the electronics with the targeted applications;
  3. Contribute to standardization and regulation issues related to this research area.

Invited speaker 1: Roberto Cibils

Ing. Roberto Manuel Cibils (INVAP SE) is an Electronic Engineer (UTNFRM 1978). He began his career with a fellowship from CONICET in INTEC for the developing of electronic devices using amorphous hydrogenated silicon. From 1984 to 1986 he joined UTNFRSF as an assistant professor of the Systems Engineering career. In 1986 he joined INVAP SE where he developed his professional activity in nuclear and space projects. Among other projects, he participated in the development of the Radiation Monitoring Systems for the ETRR-2 Multipurpose Nuclear Reactor EPC Project, Inshas, Egypt and the OPAL Nuclear Reactor EPC Project, Lucas Heights, Australia. In 2006 he joined the Systems Engineering Staff of ARSAT-1 project for the development of a geostationary communications satellite. He is author of several articles in international journals with reference and international congresses. He is also the author of several national and one international patent on radiation detection devices. He is a reviewer of international publications for the IEEE Transactions on Nuclear Science Journal. Currently he is working on a project for enabling the use of the leading edge technology of commercial electronic components in space missions.

Lecture: Space, the new frontier for the leading edge technology of commercial integrated circuits
Traditionally, satellites used electronic components designed, manufactured and tested according to standards minimizing the failure risk and maximizing their lifetime in spite of the aggressive environmental conditions to which they are exposed throughout their life cycle. The price that is paid for that benefit is not only economical, but also includes important delays and complex purchasing procedures for their supply. However, the main consequence suffered from the use of such components is technological backwardness. The use of electronic components qualified for the space environment implies greater consumption of power, greater mass and much lower processing performance than their equivalent function in commercial quality. The spread of space missions objectives has produced missions that do not have to operate in so harsh environments, neither have the extreme lifetime requirements of classical missions. Then, alternative strategies for the use of not space-qualified electronic components appears. In this talk I will describe all known mechanisms that create vulnerability in the integrated circuits and the conditions that give origin to them throughout all stages of their life cycle (design, supply, storage, assembly, test and operation); which are their common factors and how can they be avoided or mitigated.

Lithium-ion batteries are the most promising devices in energy storage, from low-power mobile applications up to megaprojects. In addition, some types of lithium-ion batteries have good performance for high current consumption in a cyclical way which makes them applicable as power storage devices basically in two fields: electric vehicles and alternative energy.

Invited speaker 3: Joel Gak

MSc. Joel Gak (UCU) Full Time Professor G.3, Universidad Católica del Uruguay. In 2005, he joined the Electrical Engineer Department, Universidad Católica. Since 2005, he has been involved in research projects in the field of CMOS analog and mixed mode design and high voltage technology.

(M’07) received the M.Sc. and Graduate degrees in electronics engineering from the Universidad Católica, Montevideo, Uruguay, in 2007 and 2010, respectively. In 2011 he become a Ph.D. student in Universidad Nacional del Sur, Bahia Blanca, Argentina

Lecture: ASICS for implantable medical devices
In this presentation the study and development of integrated circuits for the specific case of implantable medical applications, in a 0.6m HV CMOS technology on SOI wafer, is presented. The work contains innovative results obtained from working with circuits for cardiac and other stimulators, and sensors.

First, the technique of bulk degeneration will be presented for the increase of the linear range of OTAs, on which there is shortness of previous work. By means of this technique, it will be shown that lower supply voltages and less distortion can be achieved in comparison with previous published OTAs. An OTA that combines both bulk and source degeneration techniques was implemented and measured, reaching a linear range above 1V with a power supply that varies from 1.8V to 5.5V. As an application example, an amplifier and signal processing circuit was developed for a piezoelectric accelerometer aimed at physical activity estimation in a rate adaptive pacemaker, using Gm-C filters.

Finally, some circuit blocks that implement the concept of safety by being in direct contact with biological tissue, when it comes to stimulating are present. Control systems are described for safe stimulation of tissue in both voltage and current, and even a modified (safe) level shifter.
