Morning Tutorials (9:00 – 12:30)

Tutorial # 1: Fundamentals of Battery Chargers

With the expanded use of portable, battery-operated electronic devices in every aspect of human life, there is an increased interest in the design of battery chargers integrated circuits. Since this area is not typically covered in graduate or undergraduate circuits’ curriculum, there is a serious shortage in researchers and engineers who have the necessary background to develop efficient and cost-effective solutions. This tutorial will introduce the basic operation and characteristics of various primary and secondary battery cells, such as Alkaline, NiCd, Li-Ion, and NiMH, including their charging/discharging profiles, self-discharging, internal impedance, and charging cycles. This will be followed by presenting the most common charging schemes used to charge single- and multi-cell battery stacks, including the pulse charging scheme, and the constant-current constant-voltage charging scheme. Linear and switching battery charger topologies, fuel gauging, and cell-monitoring and cell-balancing circuits will also be discussed, including examples of commercial implantations of battery charger integrated circuits.

Tutorial # 3 Hardware-based Security Solutions for the Internet of Things using Physical Unclonable Functions

The Internet of Things (IoT) concept consists of numerous resource-constrained devices such as sensors, nodes and actuators that are connected together and with the Internet. By 2020 it is anticipated that the IoT paradigm will encompass approximately 20 billion connected devices. The interconnection of such devices provides the ability to collect huge amounts of data which are then processed and analyzed for further useful actions. A significant portion of the transacted data between IoT devices is private information which must, in no way, be eavesdropped or tampered with. Security in IoT devices is therefore of paramount importance for the further development of this paradigm. Such devices have typically limited area and energy resources, which makes the use of classic cryptographic solutions prohibitively expensive. Physically Unclonable Functions (PUFs) are a class of novel hardware security primitives that promise a paradigm shift in many security applications; their relatively simple architectures can answer many of the security challenges of the energy- constrained IoT devices.

In this tutorial, we discuss the design challenges of secure IoT systems and how to use hardware security to tackle those challenges, then we explain the design principles of Physically Unclonable Functions, finally we discuss the reliability and security problems of PUF devices and present a number of enhancement techniques to remedy those shortcomings. The tutorial concludes with a summary of open research questions of the design of hardware-security schemes for IoT applications.

Tutorial # 4: Charge-Steering: A New Low-Power Design Methodology

Recently, charge-steering circuits emerged as a possible solution to reduce the power consumption of circuits while not sacrificing their frequency of operation. As a result, charge-steering circuits quickly became favorable substitutes for their current-steering counterparts in high-speed low-power applications. This tutorial will start by explaining the theory of operation of charge-steering circuits and how they can replace their current-steering counterparts. Three major analog/mixed-signal systems are then explained with an emphasis on how they can benefit from charge steering. The first is serial-link receivers where the use of charge-steering in slicers and equalizers is emphasized. The second is analog-to-digital converters where the focus will be on the comparator design. The third is clock-and-data recovery circuits where the focus will be on the phase-interpolator design. The tutorial concludes by discussing the advantages and disadvantages of this shift towards charge-steering circuits.

Afternoon Tutorials (13:30 – 17:00)

Tutorial # 5: Design Methodology and Circuit Techniques for Any-Load Stable LDOs with Instant Load Regulation

Application of the structural methodology to the LDO design creates a new class of circuits: any load stable, with instant transient response, large power supply rejection ratio and low noise. Presented are examples of the imbedded in SoC LDOs for the SRAM unit, (5 ns reaction time on the load steps), radio transmitter (shaping the required noise vs. frequency characteristic) and LDO for memory retention in the shutdown state (300 nA quiescent current). These LDOs can operate with or without off-chip load capacitors; they are robust to the process and temperature variations and portable to any CMOS process. The circuit techniques demonstrated during this course is proven in design of industrial circuits including LDO regulators. The particular topics covered in this tutorial include: LDO regulators, their parameters in steady-state and dynamic operation; line and load regulation; load step response; traditional topologies of LDO regulators; components of traditional regulators; the limitations of traditional one-loop regulators topologies. Characteristics of the proposed approach: Using specialized two and multi-loop structures, error-dependent biasing and nonlinear amplifiers.

Tutorial # 6: Phase-Locked Clock/Frequency Generation and Modulation

The phase-locked loop (PLL) has been a key building block in coherent communication systems. As CMOS technology advances, the traditional PLL suffers from poor scalability, loop parameter variability, leakage current and linearity problems. Accordingly, diversified PLL architectures and circuit techniques have been proposed in consideration of performance, power and cost, thus making it more difficult for circuit designers to choose the right design solution than ever. This tutorial gives some insight into PLL basics with system perspectives tailored for circuit designers, focusing on clock/frequency generation. Also, various PLL architectures (analog/digital/hybrid) and PLL-based modulation methods (1-point/2-point/2+-point) will be discussed.

Tutorial # 7: Energy Efficiency and the Internet of Things: From Circuits to Protocols

The Internet of Things has become the Internet of Everything and the Internet of All Things. It is predicted that by the end of 2020, the number of smart objects globally connected will reach 212 billion. Machine-to-machine (M2M) internet traffic is expected to reach up to 45% of all internet traffic. By its universal and all-inclusive nature, IoT growth over the past 5 years has been enabled by the development, design, and implementation of a heterogeneous set of data communication architectures. The objective of this tutorial is to give a comprehensive overview of the energy aspects of the internet of things at both the communication protocol level and at the circuit level. In particular, we survey the infrastructure protocols of the Internet of Things and show how energy efficiency has been the major concern driving their development and adoption. We further take a detailed look at the radio component of the IoT, which the major power consumer in the wireless sensor node. The existing wireless standards in the low GHz frequency range cannot cater to the needs of IoT Transceivers. Transceivers operating in these crowded bands need absolute frequency accuracy and external components such as crystals and/or resonators. In addition, the antenna size is too big to be integrated in a small package with the sensors. We illustrate why a paradigm shift is needed in the quest for ultra-low power transceivers with a minimalist design approach, without compromising robustness and providing a viable solution for IoT Transceivers.
