Design Challenges for the Internet of Things
Danielle Griffith, Texas Instruments
Abstract: The term "the Internet of Things" was first used in 1999 to refer to a network of objects embedded with sensors and wireless connectivity. By 2015, there were 5 billion of these connected devices. Within the next five years, it is predicted that there will be more than 25 billion connected IoT devices. This rapid market growth has been made possible by many innovations in connectivity standards, system architecture, power management, and circuit design. This talk will describe seven different design challenges and the solutions that have been needed for the creation of today's low power, small size, and low cost wireless sensors nodes. These challenges include reducing sleep current, improving power management efficiency, improving the sleep timer frequency stability, reducing start-up time, connectivity standard optimization, reducing active power, and removing external components. The impact of each improvement to the over all system performance will be described, as well as examples of state-of-the-art designs in each of these areas. Further advances that are needed to continue this market growth will also be presented.

3D Integration - Challenges and Advantages
Malgorzata Chrzanowska-Jeske, Portland State University
Abstract: 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 ICs) consisting of multiple layers of systems integrated vertically using through silicon vias (TSVs). We will discuss advantages and challenges of current 3D TSV-based technologies and how to exploit various options through tradeoffs and well-educated choices for designing energy efficient heterogeneous systems. Comparisons between various TSV models and layout solutions will be presented and discussed. Influence of TSV-induced thermo-mechanical stress on devices and interconnects will be discussed. Influence and design trade-offs of temperature distribution on system performance and power dissipation will be discussed. As time permits we will also look towards the horizon, exploring monolithic 3D systems, a variety of new materials such as carbon-nanotubes, and the potential of an abundance of energy efficient interconnects.

Bringing Cores Closer Together: The Wireless Revolution in On-Chip Communication
Partha Pande, Washington State University
Abstract: The continuing progress and integration levels in silicon technologies make complete end-user systems on a single chip possible. This massive level of integration makes modern manycore chips all pervasive in domains ranging from weather forecasting, astronomical data analysis, and biological applications to consumer electronics and smart phones. Network-on-Chips (NoCs) have emerged as communication backbones to enable a high degree of integration in manycore platforms. Despite their advantages, an important performance limitation in traditional NoCs arises from planar metal interconnect-based multi-hop communications, wherein the data transfer between far-apart blocks causes high latency and power consumption. The latency, power consumption, and interconnect routing problems of NoCs can be simultaneously addressed by replacing multi-hop wired paths with high-bandwidth single-hop long-range wireless links. In this talk, we will present design of the millimeter (mm)-wave wireless NoC architectures. We will present detailed performance evaluation and necessary design trade-offs for the small-world network-enabled wireless NoCs with respect to their conventional wireline counterparts in presence of both conventional CMP and emerging big data workloads. We will discuss how Machine Learning can be exploited to design energy efficient Wireless NoC architectures. We will finish this presentation by discussing how the wireless NoC paradigm can enable realization of datacenter-on-chip using heterogeneous processing cores.

Supply Voltage Noise and Mitigation for Real World SoCs
Visvesh Sathe, University of Washington
Abstract: The past decade has seen a great deal of attention and effort focused on circuits, architectures and methodologies for energy-efficient and low power computing across a broad range of applications from ultra-low power devices to high-end servers. As designers continue to seek and evaluate low power technologies to enable the next generation of computing, the traditionally unheralded problem of voltage margin minimization has emerged to become one of the most significant sources of inefficiency and dissipation. Real-world integrated systems are margined, or guard-banded to address many sources of noise and variability including process, temperature, aging, and supply voltage noise and offsets. The trend toward multiple, fine-grained voltage domains, and aggressively voltage-scaled systems has exacerbated the problem. Voltage-margin minimization is a central component of modern low power design. Indeed, many recent low power efforts in the industry have moved beyond methodology and circuit design to address voltage margin minimization! In this tutorial, I propose a modern treatment of low-power design by actively managing supply-voltage variations. In contrast with text-book approaches, I examine a blend of well-established and emerging solutions that have proven to be effective in real-world constrained systems. The tutorial is organized in two parts. In the first, I begin by analyzing the main contributors toward voltage margins, including practical sources that are related to IC test and product deployment. A subsequent discussion on the major sources of voltage-margins is followed by an examination of a variety of circuit-architecture techniques used to directly and indirectly reduce voltage supply noise margins. High-density de-cap technology, active decap, supply-resonance avoidance, operation-throttling and adaptive clocking techniques to mitigate supply voltage noise. These techniques will be presented in the context of production designs and their constraints for a system-aware treatment of the subject. In the second section, I focus on Integrated Voltage Regulation (IVR) circuits. As designers grapple with more aggressive voltage scaling in the presence of supply variation, Integrated Voltage Regulation (IVR) has emerged as the key to achieving fine spatio-temporal control of SoC supply voltages. IVR has already been deployed for energy-efficient operation in high performance systems (Intel Haswell), and the trend to incorporate IVR to support finer voltage domains continues. We examine recent developments and challenges in the area of integrated voltage regulation across the three major voltage regulator technologies: switching-inductor converters, switched-capacitor converters, and low-dropout (linear) regulators. This tutorial provides an overview of low power circuit and architecture techniques with a system-level context. It is designed to be readily accessible to graduate students and practicing engineers alike, with a blend of well-established and emerging approaches to low power design.

CMOS Integrated System on a Chip for Neural Interface Applications
Jacques (Chris) Rudell, University of Washington
Abstract: The last decade has seen an explosion in research efforts which attempt to miniaturize rack-mounted, neural interface electronics to a form that is easily implantable for in vivo applications. Commensurate with this trend, neural scientist and engineers are demanding higher performance electronics for neural stimulation, recording, encoding, communication and energy harvesting, all in the context of a closed-loop neural interface. Single-chip integration of all the desired electronics appears to be the obvious solution for practical Bidirectional Brain Computer Interfaces (BBCI). However, challenges remain to realize a closed-loop neural interface which must utilize minimal energy, produce high voltages and suppress unwanted spurious signals which are created by “simulation artifacts.” This presentation will start with an overview of integrated neural interface electronics and conclude with a description of some recent work conducted at University of Washington’s Center for Sensorimotor Neural Engineering (CSNE).

The Design Challenges for Self-Powered Wireless Wearable ECG Sensor SoC
Yong Lian, York University, Canada
Abstract: According to the World Health Organization's 2008 report, the top three leading causes of death worldwide are coronary heart disease, cerebrovascular diseases, and lower respiratory infections. Governments and biomedical companies are pouring millions of dollars into research and development to find solutions for these diseases, and technological platforms to support disease management. Wireless biosensors are one such platform, with their ability to measure and communicate parameters that indicate the presence, or onset, of pathology. According to the report from Wearable World, the wearable market for mobile health applications and associated devices will grow at a compound annual growth rate of 61% to reaching $26 billion in revenue by 2017. By any yardstick, this is an explosive trajectory. Yet, the development of wireless biosensors faces huge challenges. So far there are no satisfactory solutions for reliable real-time monitoring of vital signs such as electrocardiogram, blood pressure and, oxygen saturation, not to mention other important parameters such as cardiac output, vessel level flow, glucose, or drug levels to name but a few. This tutorial will cover several topics related to challenges in the design of self-powered wearable wireless biomedical sensor chip including regulatory requirements, skin-electrode interface, design considerations of analog frontend, ADC, signal processing, and wireless transceiver. The focus is on the development of self-powered wearable wireless biomedical sensor SoC, low power techniques and system architecture. Design example, such as self-powered wearable ECG sensor, will be discussed in detail.

ADC Design – From System Architecture to Transistor Level Design
Bhibhudatta Sahoo, University of Illinois, Urbana-Champaign
Vishal Saxena, University of Idaho
Abstract: Pipelined and Delta-Sigma (ΔΣ) ADCs are increasingly becoming popular in mixed-signal system-on-chip (SoCs). This tutorial combines theoretical as well as practical perspectives on ADC design with special focus on two types of ADCs, viz., CT-ΔΣ ADC and pipelined ADC. The goal is to provide a complete picture to the audience, starting from system level architecture to their transistor-level design. The tutorial will cover basics of ΔΣ modulation, both continuous-time (CT) as well as discrete-time, and pipelined ADCs. System-level behavioral modeling using Matlab/Simulink environment will be presented. The top-down design approach will discuss circuit implementation and include circuit non-idealities in the behavioral modeling. Case studies will be presented for CT ΔΣ ADCs and various digital calibration techniques for pipelined ADCs.
ΔΣ ADCs can be implemented either using discrete-time (switched-capacitor) loop-filter or a continuous-time loop filter. These two implementations have their own advantages and disadvantages. While discrete-time (DT) ΔΣ ADCs are well understood and popular in industrial designs, continuous-time (CT) ΔΣ ADCs have gained a considerable amount of interest in the academic community, followed by early industrial adoption. CT-ΔΣ ADCs are becoming an attractive architecture in broadband wireless communication systems due to several desirable features including inherent anti-aliasing filtering (AAF), relaxed bandwidth requirements of the active elements and much lower power consumption. However, there are few challenges in the widespread adoption of CT-ΔΣ ADCs in industrial designs due to the design complexity resulting from a hybrid CT and DT system, and sensitivity to clock jitter and RC time constant variation.
Pipelined analog-to-digital converters are commonly used for applications that require high-speed and resolutions of approximately 8-14 bits. They present significant advantages compared to high-speed flash ADCs, that require large number of comparators, and high-resolution successive approximation ADCs, that require large number of clock cycles. Since, switched capacitor circuits are the primary building blocks of pipelined ADCs, the accuracy and linearity of pipelined ADC is limited due to capacitor mismatch, finite op amp gain, and op amp nonlinearity. Various methods like trimming, error averaging, etc. have been used in early days to address the accuracy and linearity limitations in pipelined ADCs. These techniques can be categorized as analog calibration techniques. Aggressive device scaling, resulting in high-speed and low-power digital circuits, have led to the adoption of digital calibration techniques to realize high-speed, low-power, and high-resolution pipelined ADCs.
