Room Giralda 1-2

Abstract

Many recent applications in biomedical devices, Internet of Things, security systems, automotive instrumentation, and other important structures call for sensor networks. Applications in these areas require high-performance pervasive sensors with adequate energy/power sources, mixed-mode signal processing and digitization, and effective communication networks. This tutorial will broadly focus on challenges and opportunities in pervasive sensor networks. The first talk will discuss the implementation of CMOS-based sensor platforms and heterogeneous integration approaches for several optical, chemical, and biological sensing applications. This will be followed by a tutorial description of incremental analog-to-digital converters; these are particularly effective in sensor and actuator analog interfaces, where they can provide very high accuracy, low latency, and simple digital post-filtering, and are easily multiplexed for multi-sensor systems, such as imagers and brain wave detectors. The most recent implementations of such data converters will be discussed, along with the most efficient design techniques.

A recent innovation in the design of energy-efficient high-performance CMOS amplifiers was the introduction of ring amplifiers. The next tutorial will include a description of the operating principles and design of these circuits, along with various implementation examples relevant to low-power and high-resolution digitization of sensed parameters.

Wireless communication between sensor nodes and gateway is critical for practical network deployments. The last talk will focus on enabling battery-less sensor systems with wireless communication capabilities. We will present RF-powered wireless sensor nodes in the context of size and weight limitations, and present design approaches to maximize RF-energy harvesting. The underlying IC-antenna co-design techniques will also be translated to the design of low-power wake-up radios for low-power sensor networks.

Abstract

Analog-to-digital converters incorporating VCOs and TDCs are a good alternative to switched-capacitor Sigma- Delta modulators for low-power sensor, biomedical and communications applications. As main advantages, they are mostly digital and suitable to be integrated along with digital logic in a nanometer CMOS SoC. One of the main problems to their widespread use is their intrinsic differences to designing switched-capacitor circuits, which forces analog designers into a total paradigm change. The aim of this tutorial is to show the design methodology of such time-based ADCs from the basics to the latest developments. Most analog designers might notice some resemblance to PLL design. The tutorial will clearly highlight the differences to standard PLL circuit design and will illustrate the design methodology with practical circuit design examples.

AM-2. Always-On Integrated Circuits and Systems down to nWs – Enabling a Greener and Smarter World with Nearly No Batteries

Abstract

Batteries are well known to pose fundamental threats to the further advancement of systems for ubiquitous sensing and intelligence (e.g., Internet of Things, devices for healthcare, smart objects/systems). Batteries are indeed a major cost and form factor bottleneck in single-chip integrated systems, and will also have a heavy environmental impact when deployed (and disposed) at the expected scale of one trillion connected devices. Accordingly, research programs and startups focusing on battery-lightweight or battery- less operation have recently flourished, aiming to enable a new breed of integrated systems with millimeter-range form factor, always-on operation, and sub-dollar cost.

In this tutorial, the principles and the available state-of-the-art techniques for battery-lightweight and battery-less integrated systems with always-on operation are introduced. From a top-down viewpoint, system architectures are introduced to enable continuous adaptation to workload, harvested power/battery energy availability and targeted output quality, under limited or no battery energy. Time- and event-driven frameworks are introduced and exemplified with several silicon demonstrations, along with duty-cycled and always-on schemes. From a bottom-up perspective, circuit principles and advanced techniques are introduced to enable uninterrupted operation under an uncommonly wide range of available harvested power, and/or very limited battery energy. The tutorial covers all major sub-systems along the on-chip signal chain, from energy harvesting to power delivery, analog interfaces, digital processing, and higher-level signal sense-making. Edge computing, machine intelligence and in-memory computing are shown to be crucial in the enablement of continuous event monitoring and efficient energy usage at the system level. The related concepts are exemplified by integrated prototypes from industry and academia, both in bulk and FD-SOI technologies. Experimental results from internal research are also shared to gain a deeper insight into available opportunities in battery-less integrated systems.

At the end of the tutorial, the attendees will gain a solid understanding of the fundamental requirements, the basic design principles, and the state of the art in battery-lightweight or battery-less systems.

Abstract

With exponential increase in the amount of data collected per day, the fields of artificial intelligence and machine learning continue to progress at a rapid pace with respect to algorithms, models, applications and hardware. In particular, deep neural networks have revolutionized the field by providing unprecedented human-like performance in solving many real-world problems such as image or speech recognition. There is also a significant research aimed at unravelling the principles of computation in large biological neural networks and, in particular, biologically plausible spiking neural networks. Research efforts are also directed towards developing energy- efficient computing systems for machine learning and AI. New system architectures and computational models from tensor processing units to in-memory computing are being explored. Reducing energy consumption requires careful design choices from many perspectives. Some examples include: choice of model, approximations of the models for reduced storage and memory access, choice of precision for different layers of networks and in-memory computing. The half- day tutorial will provide a detailed overview of the new developments related to brain-inspired computing models and their energy-efficient architectures. Specific topics include: (a) Computing models: Perceptrons, convolutional neural networks, recurrent neural networks, spiking neural networks, Boltzmann machines, hyper-dimensional computing; (b) backpropagation for training, (c) Computing architectures: systolic arrays for convolutional neural networks, low-energy accelerators via sparsity, tensor decomposition, and quantization, in-memory computing.

Abstract

The future of healthcare relies on the integration of personalised medicine in our daily lives, identifying illnesses rapidly and providing data to assist doctors in deciding on a suitable treatment. One avenue of research for such technology involves leveraging on the semiconductor industry, where advances have allowed to continuously push down the boundaries of scalability, robustness, computational power, affordability and miniaturisation. Sensors implemented in a Complementary Metal-Oxide-Semiconductor (CMOS) process have shown promises for integration with computational processing hardware on the same substrate. This has been the case for the Ion- Sensitive Field-Effect Transistors (ISFETs), which rely on a similar structure to the standard MOSFET and as such can be included as part of classical CMOS analogue front-end architectures. Thousands or millions of these sensors can then be integrated on the same microchip, leading to the design of full System-on-Chip (SoC) architectures for real-time ion imaging.

This tutorial will discuss implementation of the ISFET in unmodified CMOS technology, emergent trends in ISFET instrumentation and successful cases of integrated ISFET-based Lab-on-Chip (LoC) platforms. It consists of four parts:

• ISFET physics, operation and non-idealities in unmodified CMOS

• Design of analogue ISFET front-end architectures

• Methods for addressing ISFET non-idealities

AM-5. Body Area Network – Connecting Things Together Around the Human Body

Room España 5

Abstract

Chronic diseases account for over 1/3 of deaths around the world. To mitigate the impact of such diseases, healthcare paradigm is now shifting from reactive illness management towards proactive and preemptive health management; the goal here is to maintain a healthy life in the first place or to prevent illness from getting any worse by continuously monitoring health during normal daily life. Body Area Network (BAN) is an attractive means for continuous and pervasive health monitoring, yet its unique and harsh environment gives circuit designers many challenges. As human body absorbs the majority of RF energy around GHz band, existing RF radio may not be an ideal for communications between and on-body sensors.

In order solve the issues, this tutorial presents the Body Coupled Communication (BCC)-based BAN. BCC BAN utilizes human body itself as a communication medium, which has orders of magnitude less pathloss when compared to RF based BAN. We will cover three types of BCC-BAN: 1) capacitive coupling, 2) magnetic coupling and 3) galvanic coupling. For each type, we will explorer its channel characteristics, followed by design considerations and transceiver implementation examples. I will then discuss what circuit designers should consider in such non-conventional environments. Low energy circuit techniques to overcome their limitations will also be discussed. We will then will review their various system aspects of the BAN, including powering up the wearables using the wearable BAN.

Contents

  1. Flexible Electrode and Platform: We will first explore flexible platform that enables wearable form factor electrodes and BAN sensor, namely the Planar-Fabric and Polymer Circuit Board.
  2. BAN-BCC Types: There are largely three types of BCC: 1) capacitive coupling, 2) magnetic coupling, and 3) galvanic coupling. Each type has its own strengths and weaknesses. We will review extensively pros and cons of each approach, with example applications.
  3. Circuit and Transceiver Design for BCC-BAN: We will study the transceiver implementation with circuit and system aspect design consideration. BCC-specific issues and circuit ideas to overcome such issues will be covered thoroughly. This will be directly related to the each BCC type discussed in Section 2.
  4. System and Network Formation: Finally, we will cover how to form an energy-efficient BAN with the BCC. Star topology vs. ad-hoc topology will be compared, and the MAC/Network layer design considerations will be covered. After covering the system verification, we will look in to several system examples that use the BCC Network. Finally, the tutorial will conclude with interesting aspects and opportunities that lie ahead.

Abstract

This tutorial addresses the low-power ADC design perspectives with a focus on time-domain ADCs in nanometer CMOS technologies. The tutorial is divided into two parts. In the first part, the low-power ADC design perspectives will be overviewed, including the fundamentals, architectures and low-power considerations on the block level and circuit level. In the second part, the ADC design with time-domain signaling will be discussed, starting from an overview of state-of-the-art time-based ADCs, including TDC-based, VCDL-based and VCO-based. Unique properties of time-domain quantizers will be studied, i.e., intrinsic noise shaping in delta-sigma modulators, inherent coarse quantization in Nyquist converters, metastability, trade-off flexibilities, etc. The number of oscillation cycles (NOC) are analyzed and exploited as an additional design space without extra cost in speed, power, and noise. Design examples using NOC to enhance the performance, efficiency, calibration and PVT robustness of VCO-based ADCs will be discussed.

Abstract

This tutorial presents the fundamentals of short-reach optical communication and the design of optical receivers needed to support future datacom requirements such as cost, latency, energy-efficiency, and bandwidth density. Optical links are widely deployed in data centers for links above a few meters. As data rates increase electrical links are being replaced with optical links over shorter and shorter distances with the goal of bringing the optical signal closer to the processor and memory chips. Different approaches for packaging and integration are explained along with their typical link budget. Recent advancements in photonic integration for receivers exploiting Silicon-on-Insulator (SOI) fabrication processes will presented. Examples of Silicon-Photonic(SiPh)/CMOS co-design solutions will be presented. The conflicting requirements of low power and low noise are explained as well as an overview of noise analysis. Emerging receiver architectures that give higher gain, lower noise but introduce inter- symbol interference will be presented. Attendees will also have an overview of the state of the art in receivers for PAM2 and PAM4 modulation in Silicon Photonic and Vertical cavity surface emitting laser (VCSEL)-based links.

Abstract

There is a growing need for entirely new paradigms of computing that “can proactively interpret and learn from data, solve unfamiliar problems using what it has learned, and operate with the energy- efficiency of the human brain.” In alignment with this goal, large-scale integration of CMOS mixed- signal integrated circuits and nanoscale emerging devices, such as the phase-change (PCRAM) and resistive RAM (RRAM), etc., can enable a new generation of Neuromorphic computers that can be applied to a wide range of machine learning problems. This tutorial combines an overview of recent advances in energy-efficient Neuromorphic Computing Circuits and Systems for embedded deep learning applications. The tutorial aims to provide a complete picture to the audience; from emerging devices, to transistor-level neural circuit design, and learning algorithms to put the system together. Case studies will be presented for Neuromorphic System-on-a-chip (NeuSoC) with applications to spike-based machine learning followed by recent advances in the area spiking neural networks and neuromorphic hardware.
