Workshop on micro/nanoelectronic circuits and systems

Very few social and technological revolutions in the history of humankind have become as vertiginous as the one experienced in the first decade of 21st century. In fact, it would be very difficult to explain our present society without resorting to the so-called Information Technologies, and particularly to some technological achievements such as the Internet, mobile phones and social networks. Indeed, technology downscaling toward deep nanoscale level has allowed to put billions of transistors together in a single chip, thus making it possible to integrate entire systems with increasingly number of applications, which span from consumer electronics and computing to telecom and biomedical devices.

The evolution of these technologies and their synergy with other fields of science and engineering are immersing our society into the so-called Internet of Things, in which an increasingly number of devices are being interconnected in more and more autonomous machine-to-machine infrastructures. This pervasive tendency towards a digital world, demands for efficient ways of interacting with diverse physical environments, by means of smart sensors, actuators, signal conditioning techniques and analog-digital interfaces.

In this scenario, this workshop – organized by the Spain Chapter of the IEEE Circuits and Systems Society – aims to present an overview of some recent advances in the design of micro/nanoelectronic circuits and systems in diverse application scenarios and case studies including automotive applications, smart sensing, interfacing brain and machines and flexible organic/printed electronics. To this purpose, several talks given by worldwide recognized experts in these fields will present their recent developments in micro/nanoelectronics putting emphasis on how to transfer their research and academic results to industrial products and the creation of start-ups and high tech companies.

Title: Industrial Integrated Circuit Design Techniques

Speaker: Antonio J. Lopez-Martin 

Affiliation: Public University of Navarra Campus Arrosadia E-31006 Pamplona, Spain []



The design of industrial integrated circuits (IC) in today’s advanced technologies is a challenging task that involves several relevant aspects often not considered by academic IC designers. Issues such as time-to-market, design reuse, design for test (DFT), design for manufacturing (DFM), yield, project negotiation and intellectual property management, are highly relevant and often not considered in academic projects. 

This talk will provide an introduction to the area of industrial integrated circuit (IC) design. It is mainly aimed academic researchers with little or no experience on industrial IC design that want to get involved eventually in the development of commercial IC design projects. Focus will be on practical aspects of industrial IC development, based on the experience of the author in research and development projects with various companies. A detailed case study of an ASIC developed by the author for contactless angular detection in automotive applications will serve to illustrate the different concepts treated in the talk.

Title: How to Make Your Integrated Sensor Smarter

Speaker:Francisco Serra-Graells

Affiliation: Integrated Circuits and Systems group, IMB-CNM(CSIC); Dept. Microelectronics and Electronic Systems, UAB []



More than Mooreroadmaps predict a semiconductor market evolution towards new heterogeneous integrated system-on-chip products with built-in input and output transconductors. Unfortunately, it is not uncommon to find several examples of very promising sensors that could not fill the gap between sensor prototypes (devices) and final products (systems) due to the lack of suitable custom CMOS interfaces (circuits). This tutorial will introduce the design challenges associated with these read-out circuits, such as massive multichannel A/D conversion, sensor biasing control loops, tuning capabilities against technology deviations, and calibration strategies, as well as some other practical aspects related with the powering and packaging of full smart sensors. The low-power and compact area CMOS readout integrated circuit (ROIC) proposals presented in this tutorial are taken from real smart sensors examples developed at IMB-CNM(CSIC) for applications such as fast clinical analysis, toxic gas classification, portable chemical sensing, infrared and X-ray imaging and remote powered sensing nodes.

Title: Printed MicroElectronics: From Technology to Design, Rebuilding the Path

Speakers:Eloi Ramon, Jordi Carrabina, Lluís Terés

Affiliation: Universitat Autónoma de Barcelona, IMB-CNM, (CSIC[]



While silicon based technologies are evolving towards very advanced nanometric nodes (≤ 20ηm.), the emerging thin-flexible-organic-large-area electronics (a.k.a. printed electronics, PE) based on flexible substrates and functional inks are starting again the history of microelectronics at technology and device levels trying to grow up to applications looking at the silicon path but far away from its costs and performances.

Performance and size of PE devices are far away from Si devices; nevertheless there are a lot of new applications which have been enabled by those new technologies where the rigid silicon/PCB electronics doesn’t have sense according to large area requirements (i.e. large area sensors), low cost (i.e. RFID tags or biosensors) or flexibility (i.e. wearables). In case that high performance is required the proposed solution is hybridization by using low temperature “silicon-to-foil assembly processes” while keeping the overall system flexibility. 

A successful and reliable process for printed devices is a key challenge for the concept of Printed Electronics. After reviewing the main printed-electronics technologies we will summarize the key characteristics, performances, cost factors and application domains for each one in order to keep clear these basic concepts around them. 

This presentation will also report the manufacturing and electrical characteristics of devices and circuits using printing deposition techniques and taking into account the yield, the usage of industrial relevant technologies and reporting about the manufacturing of electronic components such as resistors, conductive tracks, capacitors, inductors and transistors.

Following the Si microelectronics experience we have proposed a methodology to go from early technology development stages up to physical design kit (PDK) and reusability-based design flows by means of PCells-based developments for basic technology structures, devices and std.cells or even gate-array strategies. Such a methodology has been applied to three different technologies (ink-jet, gravure and evaporation based processes).
