Much of our economy and way of living will be affected by nanotechnologies in the decade to come and beyond. Mastering materials at the molecular level and their interaction with living matter opens up unforeseeable horizons. This talk deals with how we will conceive, design and use nanosystems, i.e., integrated systems exploiting nanodevices. Whereas switching circuits and microelectronics have been the enablers of computer and communication systems...
Data converters are relevant interfaces of RF circuits. It is essential to be aware of architecture, conversion algorithm and functioning because they influence the overall operation of the RF section of any communication system. The lecture will focus on key architectures of A/D and D/A CMOS converters and the performance that they can achieve with state-of-the-art technologies. Then, recent implementations...
A brief discussion on what Class- D amplifiers are as well as the different types and applications are introduced. Then the low power amplifiers suitable for portable equipment are presented. In particular, Class-D amplifiers based on hysteretic sliding mode controller, which avoids using conventional triangular carrier signals. In this family we discuss the use of two- and three-level modulated signal. A recently Class-D published last July which...
Electronic Design Automation (EDA) at the core of Electronic Design and Manufacturing Electronic systems are part of our life; they are present everywhere and in all activities we perform during the day. Today we interact with at least 350 electronic systems per day. Electronic systems are composed by hardware and software. The hardware component of those systems is made with one or more integrated circuits connected on a board. Those integrated circuits contain hundreds of millions of transistors, one of the biggest has 1 billion (1,000 millions) of transistors. Another important factor of current integrated circuits is their speed without compromising...
In order to understand the civilizations of ancient Peru it is important to realize that they developed in isolation from the other cultural centers in the world. This realization implies that whatever happened in India, China, Egypt, Mesopotamia or the Mediterranean area, had no effect here and vice versa, and thus, that everything we see as material expressions of the ancient civilizations in the Americas was independently invented and developed. Monumental architecture, irrigation, ceramics, metallurgy, domestication of animals and plants, medicine, etc. was invented in...
The objective of this tutorial is to develop the basic elements of switching circuits for analizing the dinamic behavior and designing controllers for DC-DC converters. The tutorial is oriented to advanced students and Electrical Engineers with basic knowledge of electronics, power electronics and control systems, that want to have deep understanding of...
A continuous trend of increased integration of system components on a single die creates numerous design challenges for current integration technologies like System-on-Chip (SoC). Energy efficiency is the most significant challenge for continued integration of systems, and 3D integration is one of the best hopes for realizing Moore’s Law and enabling true integrations hybrid systems possibly using a variety of materials such as III-V semiconductors and carbon nanotubes. Three-dimensional integrated circuits (3D ICs) consist of multiple layers of (electronic) circuits integrated vertically with help a variety of integration technologies. This is in sharp contrast to traditional ICs with transistors only on the...
CMOS imagers are complex systems whose design require quite different pieces of expertise, namely: pixels, analog signal processing, pixel readout and analog-to-digital conversion, digital signal processing, output drivers, etc. Confronting the design of new imagers require hence the concourse of multidisciplinary teams. However, because correct operation call for the close interconnection among the different parts, global knowledge is mandatory for successful design. This is particularly pertinent for the newer generations of smart imagers required for high-end applications and/or requiring ultra high image capture, on-chip image correction, scene interpretation, high dynamic range capture, etc. All these features demand...
