nonreturn to zero (NRZ). This NRZ format performs well at
lower data rates, but pulse amplitude modulation-4 (PAM-4)
is used for higher data rate applications; however, PAM-4 has
higher receiver sensitivity and a complex architecture. Often,
equalization with higher-order filters is employed in these
techniques, but this is effective only up to 10 GB/s or less.
For higher data rates, their performance degrades and the
number of tap coefficients required for optimal equalization
increases. In this workshop, an adaptive equalization
technique of a multigigabit backplane channel applications
using duobinary signaling for data rates from 10 to 40 GB/s,
is discussed. The main advantage of the duobinary format is
seen in the fact that its signal spectrum can be limited to half
the clock rate of NRZ format.

Title: "Passivity and Causality Issues on High-Speed Interconnects"
Abstract: This workshop will focus on the passivity and
causality enforcement techniques in high-frequency circuits
and systems. Passivity is very important in signal integrity
and is also a vital property of a system when it comes to the
stability analysis of the system. A system that is nonpassive
but stable while interfacing with a stable system may lead the
entire system to the verge of instability. This makes passivity
restoration a critical aspect in the high-frequency operation
of devices. Circuits are mostly characterized by scattering
parameters (S-parameters) in high-frequency operations. A
circuit can become nonpassive and also noncausal because
of errors during measurement of S-parameters or modeling.
Therefore, passivity and causality restoration algorithms
are deemed critical in many cases of circuit analysis and
simulation. This workshop will first discuss the background
theory of passivity and introduce a new efficient technique
of passivity restoration based on finding the local minima
of singular values. The regions between pairs of adjacent
local minima will be scaled down when the adjoining
maximum is greater than one, thus restoring passivity. The
proposed new technique for passivity enforcement has the
potential to restore the passivity in a real or simulated system
represented by S-parameters without making significant
changes in the system's original S-parameters or the systems
characteristics. Furthermore, a causality verification algorithm
is discussed, along with its implementations, on the systems
in which passivity was restored. This workshop is based on
research done by Dr. Morales's graduate student.

Title: "A Moore's Law for Mobile Power"
Abstract: The IEEE CE Society Future Directions Committee
has launched an effort with other IEEE Societies to create an
initiative for Safe Advanced Mobile Power. This talk will discuss
the initiative and how it will lead to more sustainable power
sources and mobile CE products while meeting important
requirements for safety, sustainability, manufacturability,
and cost. The objective of this initiative is to promote the
development of a technology to supply energy needs for
a week's worth of "normal" mobile device use without
recharging from a fixed power source. Green technology and
sustainability are important topics of consumer devices. Many
consumer products are "sold" as green, but how green are they
really? This presentation addresses the greenness of a number
of consumer products.

Title: "The Internet of Things: The Good, the Bad, and the Ugly"
Abstract: The IoT promises to transform our personal
and professional lives. One could foresee that we are going
to have sensors implanted everywhere, in our homes, cars,
the workplace, and even on and inside our bodies. These
sensors could communicate with one another, with bigger
computers and even with people. This has the potential of
improving health care, car maintenance, home management,
work, and life. However, as everything has advantages and
disadvantages, the IoT has them too. It raises, for example, the
potential of disruption from faulty sensors, malicious cyber
attacks, and by simply having too much data (that is difficult
