KEYNOTE I
ized near-threshold computing and memory blocks in order to deploy ultra-low power (ULP)
multi-core processing architectures for automated bio-signals analysis on WBSN. To illustrate the effectiveness of this approach, this talk focuses on cardiac and multi-parametric
monitoring systems and show how it is possible to achieve wearable ULP electrocardiogram
(ECG) arrhythmia detection systems and multi-parametric wellness monitoring devices that
can operate autonomously for long periods of time and support a graceful quality degradation of the system output based on the available power in the system at each moment in time.

Friday 27th February, 9:00 - 10:00, Sala Reconquista
Data converters are essential elements for new advanced applications like gigabit Ethernet,
optical communications, radar, set-top box, ultra wide band communications, broadband
satellite receivers, and more. The resultant specifications establish an unprecedented combination of speed, resolution, and power efficiency. The use of modern nanometer CMOS
technologies and digital assisted method are key for obtaining proper results, especially
when the requirement is to operate at conversion speed in the GS/s range. For those extremely high-speed traditional power-hungry flash architectures have been recently replaced by time interleaving power effective A/D converters. The preferred single channel
schemes are the SAR or the folding flash architecture.

“Data Converters: the road from hundred of MS/s to many GS/s”
University of Pavia, Italy
Therefore, presently, the road from hundred of MS/s to many GS/s ADC starts from highspeed SAR or equivalent power effective schemes and goes through techniques for making
effective the interleaved architecture. Namely, methods for a suitable clock generation, its
distribution and the correction of clock skew are necessary.
This presentation discusses state-of-the-art silicon implementations of high-speed single channel ADC and presents analog and digital techniques used to make the interleaved
scheme accurate and affordable.

“Reliability Issues in CMOS, and Spin-Based Design Beyond CMOS”
SACHIN SAPATNEKAR
University of Minnesota, USA
As CMOS technologies have shrunk to the scale of about ten nanometers, reliability and aging problems have emerged as a major challenge in the design of parts used in the mobile
infrastructure, server, and automotive segments. A true reliability solution must link device
models to circuit techniques to architectural approaches. Current approaches based on projecting device-level models are often pessimistic (in some cases, by orders of magnitude)
because they ignore the inherent resilience of circuits to reliability failures. At the other end
of the spectrum, system-level models often ignore the physics of reliability. This talk will first
discuss research that allows modeling, design, and design automation at various levels to
meet in the middle to solve reliability problems at various levels of design abstraction.
Even with enhanced reliability, further scaling of CMOS circuits is likely to eventually become impractical. In the final segment of this talk, we will discuss options for a post-CMOS
era, with specific focus on spintronics, an exciting prospect for post-CMOS electronics. This
model of computing is based on the use of electron spin as a state variable, instead of charge
as in CMOS, and is based on switching nanomagnets. An overview of methods for building
memory and logic devices using spin-based devices will be provided, with projections for
future research in this area.

“Designing Multi-Parametric Wearable Monitoring Systems
for Scalable Healthcare”
DAVID ATIENZA
PANELS
Embedded Systems Laboratory (ESL), EPFL, Switzerland
Latest progress in microelectronics have enabled the miniaturization of processing elements, radio transceivers and sensing elements of a large array of physiological phenomena. This situation has made plausible to realize low cost, low power, miniaturized, yet, smart
sensor nodes needed to develop wireless body-area sensor networks (WBSN). However, the
inherent resource-constrained nature of these systems, coupled with the harsh operating
conditions and stringent autonomy requirements, pose important design challenges to make
them provide automated analysis for complex biological signals. This talk discusses the use
of WBSN systems to build scalable healthcare ecosystems. Hence, it addresses system-level
design of next-generation smart WBSN platforms for personal health monitoring systems,
and highlights the unsustainable energy cost incurred by the relatively straightforward wireless streaming of raw sensor data. To achieve the extended autonomy required by long-term
ambulatory monitoring, this talk advocates for enabling more embedded intelligence onboard
these sensor nodes through a new system-level design approach. This approach exploits the
bio-signals features to apply the new compressive sensing paradigm in the design of special-

TUTORIAL I
“Subthreshold CMOS design”
CARLOS GALUP MONTORO AND MARCIO CHEREM SCHNEIDER
The use of semiconductor devices and passive components such as antennas, inductors and
transmission lines is everyday more important in the design and fabrication of integrated circuits for high-frequency applications. Circuit and system applications employing wireless communications are used nowadays for a wide variety of applications, and the trend clearly shows
that these types of circuits will be needed for a host of novel applications in the years to come.
This tutorial spans three fundamental aspects of semiconductor and passive devices for
high-frequency applications; their underlying physics, modeling and characterization. During the first part, the particular structure is analyzed with the aim of identifying the physical
mechanisms on which its performance is based, such as material properties, geometric factors and construction. A second part illustrates the different methodologies available to relate the physical phenomena to an electric equivalent circuit, addressing the need for reliable
and trustworthy models for the simulation stages of these devices. The final part of the tutorial focuses on device measurement in the high-frequency regime, covering topics such as
calibration techniques, de-embedding procedures, data transformation and interpretation.
The tutorial concludes with general guidelines for the design and analysis of semiconductor and passive elements, including parasitic effects which affect the performance of these
devices when the operation frequency is in the GHz range.

TUTORIAL III
The main purpose of this tutorial is the design of integrated circuits for ultra-low-voltage
and ultra-low-power operation. In order to focus on circuit design rather than on the complete MOSFET model, we will emphasize the subthreshold operation of the MOS transistor.
Ultra-low-voltage circuits have gained considerable attention in recent years because of the
emergence of small batteries and self-powered applications. The main solution to reduce
the energy consumption of electronic circuits is to lower the supply voltage. Theoretically, the
minimum supply voltage for a CMOS inverter is 2 (ln2) (kT/q) = 36 mV at room temperature,
as shown by Swanson and Meindl in 1972.
In this tutorial we analyze CMOS logic gates and the Schmitt Trigger circuit in weak inversion
operation, and discuss circuit techniques to approach the theoretical low voltage limit. For
analog circuits the minimum supply voltage is usually considered higher than the minimum
necessary for the operation of digital circuits. Contrary to this common belief, we will show
that analog circuits such as rectifiers and oscillators can operate with supply voltages below
(kT/q). In the lecture we will discuss key concepts for ultra-low-voltage operation, such as
MOS transistors with zero or near zero threshold voltage, modeling issues, and ultra-lowvoltage biasing and building blocks. Finally, a section on ultra-low-voltage circuits for energy
harvesting is presented.

“Implantable Neural Recording Interfaces”
MANUEL DELGADO RESTITUTO
Instituto de Microelectrónica de Sevilla (Univ. Sevilla - CSIC), Spain
Besides fostering advances in neuroscience, wireless neural prostheses for the measurement of intracranial neural activity are expected to play a significant role in the development
of novel treatments for some neurological diseases and in the implementation of untethered
brain-machine interfaces. As long as these prostheses are implanted, they have to achieve
and maintain stable long-term recordings so that the need for re-surgery is essentially eliminated. This poses important challenges on the hardware implementation of the prostheses
as they have to exhibit ultra-low power consumption, not only to prevent from harmful effects in the brain but also to minimize energy requirements; low form factor; versatility, to
prove useful in different scenarios as determined by neurologists; and adaptability to deal
not only with the intrinsic statistical deviations of the fabrication process but also with the
non-stationary nature of the electrode-tissue interface.
This tutorial surveys some of the most recent advances in the implementation of wireless
neural prostheses covering different disciplines; since the fabrication of microelectrodes, to
the design of communication protocols, passing though the optimization of ultra-low power
analog front-ends and power efficient data converters. As a demonstration vehicle, an integrated 64-channel neural recording sensor suitable for acquiring Local Field Potentials
(LFPs) and Action Potentials (APs) will be described in detail. In this prototype, an on-chip
9
dedicated processor defines the operation mode of the channels and implements a fullduplex protocol for data transmission through a wireless link. In one operation mode, the
recording system can be configured to detect and compress neural spikes so that feature
vectors instead of raw signal samples are transferred. In another mode, the system runs
a self-calibration mechanism which automatically adapts the filter bandwidth and the gain
setting of the channels. The sensor also offers different alternatives for raw data transmission in which the number of active channels and the effective sampling rate are traded-off. In
all cases, the total throughput rate of the sensor keeps below 4Mbps as imposed by the wireless link. The sensor has been fabricated in a 0.13 µm standard CMOS process and consumes
330 µW from a 1.2 V voltage supply in the most power demanding mode.

“3D ICs - Challenges and Advantages”
MACIEJ OGORZALEK
Department of Information Technologies, Jagiellonian University, Poland
The most significant challenge for continued integration of complex systems is energy efficiency. 3D heterogeneous stacking of diverse circuit blocks is one of the most promising solutions.The tutorial will focus on three-dimensional integrated circuits (3D lCs) consisting of
multiple layers of systems connected vertically. We will discuss advantages and challenges
of current 3D TSV-based technologies and other types of connections available in news technologies such as carbon nanotubes. One can exploit various options and choices for silicon
and heterogeneous systems. Challenging questions include system types, functionalities,
the variety of materials, TSV-based vertical integration technologies, 3D layout and routing,
interconnect modeling, the system 3D architecture, energy efficiency, technological feasibility, and the multi-objective optimization. Comparisons between various solutions will be
presented and discussed. An overview of current new concepts for construction of heterogeneous layers on chip containing such devices as energy scavengers and energy storing
devices including hyper-capacitors and micro-batteries will be presented.
In oversampled Sigma-Delta analog-digital converters (SD ADC) analog signal is sampled
with the frequency much larger than the Nyquist frequency, which along with the quantization noise shaping, results in an high resolution compared with the traditional ADCs. This
process is done in the modulator, which is the most critical block of the overall ADC. The
sampling rate of the oversampled signal at the output of modulator, must be decreased to
the Nyquist rate (decimated) and the out-of-band components of the quantization noise must
be removed. However, the decreasing of the sampling rate may introduce the aliasing which
must be eliminated in order to prevent the distortion of the oversampled signal. Consequently, the main part of the decimator is the digital filter, called decimation or antialiasing filter,
which has to prevent the aliasing effect. The decimation is usually performed in different
stages. The most critical is the first stage because it works at high input rate. Due its simplicity, comb filter structures are frequently used at the first stage of decimation. New demands
on SD ADC pose the strong conditions for the comb decimation stage, requiring high decimation factor, low power and area consumption. Additionally, the magnitude characteristic must
have high alias rejections and a low passband droop to avoid the degradation of the signal
after decimation.
In the first part, we will explain the effect of aliasing in the time and frequency domain and
we will introduce comb filter, which is the simplest decimation filter. We will present the advantages and disadvantages of the comb filter and its two principal structures: recursive and
nonrecursive. We will also introduce the polyphase decomposition, which is useful to move
the filtering to lower rate. We will present principal methods for the improving the magnitude
characteristic of the comb filter in the passband, the stopbands, and in both: passband and
stopbands.
In the second part, we will discuss the implementation issue and how to measure the consumed power and used area in comb-based structure. We will present power efficient and
area efficient structures, as well as the structures with best trade-off between power and
area efficiency.
