An Overview of Modeling Technologies for
Linear and Nonlinear Electronic Devices
Nowadays, computer aided design plays an unavoidable role in electronic circuit design, whether because practical linear systems are too complex to be handled by pencil-and-paper, or just because the system is inherently nonlinear and thus no closed form analysis or design solutions are possible. However, either the design engineers have a minimum understanding of what are the simulators’ possibilities and limitations, or they may turn their computer aided design tasks into tiring and time-consuming torments.
This tutorial on modeling technologies for linear and nonlinear electronic devices addresses this challenge starting by a glimpse of the most common circuit simulation tools, to then focus on their most important bottleneck: the electronic devices models. Having in mind the widely known aphorism that all models are wrong but some are useful, we will begin with the very basic concept of a mathematical model and its two most important strategies, physics-based and behavioral modeling, and show why the equivalent-circuit models are the most widely adopted model types. Then, we will discuss the modeling tools for both linear and nonlinear, static and dynamic, lumped and distributed, electronic devices and illustrate these with examples usually found in signal integrity analysis.

ENERGY sustainability for
Net ZERO Radio Communications
Energy is central to all our activities, especially now, as electricity is needed for basic human survival. Nevertheless, the resources are limited. On certain occasions, we need to rely on the opportunity to have specific energy availability and energy on demand so that sensors, emergency communications, and ICT will continue to operate even if the energy grid is not there.
This talk will discuss the electricity generation problem and how to cope with the huge demand for ICT (Information Communication Technologies) technologies. We will address new paradigms for radio communications and alternatives to make energy available when needed and where needed. It is expected that Net Zero Radio alternatives will be available on the market in the future.

Sense #Like a Bosch:
How do our cars see the world in order to drive autonomously
Imagine you no longer have to take the tedious task of driving your car to work, to school or to the supermarket. Imagine that instead you enjoy the ride by reading a book or watching your favorite movie. Imagine that car accidents are something from the past and you can go safely from one place to the other.
This is our vision for mobility at Bosch: with development of new sensors, key technologies and functionalities we are contributing to make our cars safer and to enable autonomous driving. We invent technology for life, we are Bosch, we move Bosch!
In this session, we will focus on our recent developments in terms of the sensors that make our cars able to perceive the surrounding area. Such sensors provide the necessary information to the “brain” of the car to perceive the driving scenario, process the information and make decisions autonomously.
