Wireless technologies like GSM, UMTS, LTE, Wireless LAN and Bluetooth have
revolutionized the way we communicate by making services like telephony and Internet
access available anytime and from almost anywhere. Today, a great variety of technical
publications offer background information about these technologies but they all fall
short in one way or another. Books covering these technologies usually describe only
one of the systems in detail and are generally too complex as a first introduction. The
Internet is also a good source, but the articles one finds are usually too short and super-
ficial or only deal with a specific mechanism of one of the systems. For this reason, it
was difficult for me to recommend a single publication to students in my telecommunication
classes, which I have been teaching in addition to my work in the wireless telecommunication
industry. This book aims to change this.

study complex systems. Nevertheless, if I had to name their single most appealing

Smartphones have become a key element in providing greater user access to the
mobile Internet. Many complex applications which used to be limited to PCs, have
been developed and operated on smartphones. These applications extend the
functionalities of smartphones, making them more convenient for users to be
connected. However, they also greatly increase the power consumption of
smartphones, making users frustrated with long delays in Web browsing.

Modeling and simulation of nonlinear systems provide communication system designers
with a tool to predict and verify overall system performance under nonlinearity and
complex communication signals. Traditionally, RF system designers use deterministic
signals (discrete tones), which can be implemented in circuit simulators, to predict the
performance of their nonlinear circuits/systems. However, RF system designers are usually
faced with the problem of predicting system performance when the input to the system
is real-world communication signals which have a random nature.

Ever since ancient times, people continuously have devised new techniques and
technologies for communicating their ideas, needs, and desires to others. Thus,
many forms of increasingly complex communication systems have appeared
over the years. The basic motivations behind each new one were to improve the
transmission fidelity so that fewer errors occur in the received message, to
increase the transmission capacity of a communication link so that more infor-
mation could be sent, or to increase the transmission distance between relay sta-
tions so that messages can be sent farther without the need to restore the signal
fidelity periodically along its path.

The need to develop reliable microelectronic devices capable of operating at high
speeds with complex functionality requires a better understanding of the factors
that govern the thermal performance of electronics. With an increased demand
on system reliability and performance combined with miniaturization of the
devices, thermal consideration has become a crucial factor in the design of elec-
tronic packages, from chip to system levels.

Dear Reader, this book project brings to you a unique study tool for ESD
protection solutions used in analog-integrated circuit (IC) design. Quick-start
learning is combined with in-depth understanding for the whole spectrum of cross-
disciplinary knowledge required to excel in the ESD field. The chapters cover
technical material from elementary semiconductor structure and device levels up
to complex analog circuit design examples and case studies.

The challenges associated with the design and implementation of Electro-
static Discharge (ESD) protection circuits become increasingly complex as
technology is scaled well into nano-metric regime. One must understand the
behavior of semiconductor devices under very high current densities, high
temperature transients in order to surmount the nano-meter ESD challenge.
As a consequence, the quest for suitable ESD solution in a given technology
must start from the device level. Traditional approaches of ESD design may
not be adequate as the ESD damages occur at successively lower voltages in
nano-metric dimensions.

Electricity has been chosen as the most convenient and useful form of energy, due
to its ease of transportation over large distances and easy conversion to other
energy forms. The biggest inconvenience with electricity is that it cannot be stored
and must be utilized at the moment of generation. The storage of a large amount of
electrical energy is usually connected with its conversion to other types of energy,
which significantly reduces the efficiency of such processes. The aim of the power
system, often treated as the biggest and the most complex machine ever built, is to
deliver uninterruptible electric energy of demanded quality parameters to
consumers.
