Attendees of the Design Conference can choose from various technical sessions, based on the event location. Click on the locations, below right, to see what is available to you. Each track offers multiple sessions in two main areas, Advanced Techniques of Higher Performance Signal Processing and Reference Designs and Systems Applications.
Advanced Techniques of Higher Performance Signal Processing
System Partitioning & Design
Acquired analog signals can be manipulated and processed by either the analog or digital portions of a system, for example through filtering, multiplexing, or gain control. The analog portions of a system can typically provide reasonably simple processing at fairly low cost, power, and overhead. Digital processing can provide far greater analysis power and can change the nature of the analysis without changing hardware. However, sampling theory must be taken into account. This session will cover the signal chain basics, from signal, to sensor, to amplifier, to converter, to digital processor, and back out again.
Signal Chain Designer: A New Way to Design Online
Finding the right combination of parts to create a signal chain can be a complex and daunting task, due to time demands, unfamiliarity with various technology areas, and the mass amount of unproven solutions scattered across the web. Signal Chain Designer™ is an advanced selection and design environment that enables custom design creation and direct interactive access to more than 200 tested application circuits and verified product combinations. This session will provide an overview of the new environment, and demonstrate how it integrates with the new engineering tool: Analog Filter Wizard. This new tool provides more accurate results as it shows circuit performance with real op amps and component tolerances.
Data Conversion: Hard Problems Made Easy
Data conversion for data acquisition is a two-part process which involves sampling and then converting signals into digital values. These processes inherently remove part of the complete analog signal in exchange for the power and robustness of digital signal handling. This becomes especially difficult when trying to capture signals at the limits of the resolution and speed of our systems. In this session, learn how to design a data conversion system that minimizes the signal loss to match the signal handling requirements -- even on the hard ones.
Amplify, Level Shift & Drive Precision Systems
Amplifiers are the workhorses of data acquisition and transmission systems. They capture and amplify the low-level signals from sensors and transmitters. They can pull these signals from high noise and high common-mode voltage levels. Furthermore, amplifiers can change the signal range and switch from single-ended to differential (or the reverse) to exactly match the input range of an ADC. This session will cover the versatility and power of amplifiers in precision systems.
Frequency Synthesis and Clock Generation for High-Speed Systems
Frequency synthesis and clock generation have become key elements in all aspects of high-speed data acquisition and RF design. The primary types of frequency synthesizers, phase-locked loops (PLL) and direct digital synthesizers (DDS), will be discussed along with the applications in which each are appropriate. Detailed aspects of synthesizer design will also be covered. Other applications such as clock distribution and translation will be addressed, where we identify some problems associated with poor clocking. Examples of this will be shown along with the results of doing it properly.
Sensors for Low Level Signal Acquisition
Sensors are the eyes, ears, and touch of electronic systems that allow them to capture the state of the environment. The capture and processing of sensor inputs is a delicate process that requires understanding of the signal details. Integration of sensor functions onto silicon has brought about improved performance, better signal handling, and lower total system cost. Silicon-based MEMs sensors have opened up whole new areas and applications. In this session, the fundamental MEMs sensor concept of moving fingers that form a variable capacitor will be covered, along with how it is turned into a usable motion signal. Adaptations for multi-access sensing, rotational sensing, and even sound sensing, will be covered.
High Speed & RF Design Considerations
At very high frequencies, every trace and pin is an RF emitter and receiver. If careful design practices are not followed, the unwanted signals can easily mask those we are trying to handle. The design choices begin at the architecture level and extend down to sub-millimeter placement of traces and components. There are tried and proven techniques for managing this process. The practical issues of real system design will be covered in this session, along with ways to minimize signal degradation in the high speed environment.
Data & Power Isolation
Isolation is an integral part of many modern applications from medical to instrumentation to industrial. Most applications require the designer to integrate isolation in the design while improving performance, saving board space, increasing reliability levels, reducing power consumption and, of course, cutting cost. This session will provide an understanding of various isolator technologies, and will offer suggestions on how to address such stringent design objectives.
Reference Designs and Systems Applications
High Speed Data Connectivity: More Than Hardware
In wireless communications and data acquisition systems, there is more to consider when designing and implementing a complete solution beyond physically connecting a high-speed analog module to an FPGA platform. The right software is critical to establishing a simple interface which is necessary for practical system integration. This session will start with a top-level overview of the hardware description language (HDL) used for these types of boards and then study the specific board components and how they are used to interface to high speed ADCs/DACs. Linux device drivers for the HDL components as well as for the ADI components will be presented. This will include a short introduction into the Industrial I/O (IIO) framework, the benefits it offers, and how it can be used in end designs.
Process Control Systems
The industrial control market involves the monitoring and control aspects of both complex and simple processes. Common trends within the industry, notably the drive for increased efficiencies, better robustness, higher channel densities, and faster monitoring and control speeds, subsequently drive new technology advancements for semiconductor manufacturers. This session aims to give a broad overview into the system requirements for both field instruments (sensors /actuators) and control room (analog input/output) modules, and will demonstrate a typical I/O module configuration with HART connectivity.
High Performance DSP with Xilinx All Programmable Devices
This session includes a discussion on rapid prototyping concepts using Xilinx All Programmable FPGAs and SoCs with Analog Devices high-speed and precision products. Covered in this session will be common use cases for Xilinx devices in DSP applications that interface to high-speed analog. An overview will be provided of how Xilinx accelerates development with DSP Platforms that can be used to quickly evaluate and prototype systems which include high-speed analog, programmable logic and embedded processing. Also covered will be an introduction to Xilinx's new Vivado Design Suite development environment that shortens design cycles by providing an IP centric design flow, easy to use design analysis and debug and high-level design flows supporting C/C++ and MATLAB/ Simulink.
Instrumentation: Liquid & Gas Sensing
Liquid Sensing: Visible light absorption spectroscopy and colorimetry are two fundamental tools used in chemical analysis. Most of these light-based systems use photodiodes as the light sensor, and require similar high input impedance signal chains. This session examines the different components of a photodiode amplifier signal chain, including a programmable gain transimpedance amplifier, a hardware lock-in amplifier, and a sigma-delta ADC that can measure a sample and reference channel to greatly reduce any measurement error due to variations in intensity of the light source.
Gas Sensing: Many industrial processes involve toxic compounds and it is important to know when dangerous concentrations exist. Electrochemical sensors offer several advantages for instruments that detect or measure the concentration of toxic gases. This session will describe a portable toxic gas detector using an electrochemical sensor. The system presented here includes a potentiostat circuit to drive the sensor, as well as a transimpedance amplifier to take the very small output current from the sensor and translate it to a voltage that can take advantage of the full scale input of an ADC.
MATLAB and Simulink for Communications System Design
This session will show how Model-Based Design with MATLAB® and Simulink® can be used to model, simulate, and implement communications systems. Attendees will learn how multi-domain modeling with continuous verification and automatic code generation can dramatically reduce system design time. A QPSK receiver model will be used as an example to highlight the design flow.
Instrumentation: Test & Measurement Methods and Solutions
Tilt Measurement: Tilt measurement is fast becoming a fundamental analysis tool in many fields including automotive, industrial, and healthcare. Navigation, vehicle dynamic control, building sway indication and motion detection systems all rely on this simple, cheap and precise way of angle monitoring. MEMs accelerometers are ideally suited to inclination measurement than other methodologies. This session will address the challenges encountered when designing a dual axis tilt sensor using a MEMs accelerometer including measurement resolution, signal conditioning, single- versus dual- axis, angle computation, and calibration.
Impedance Measurement: The measurement of complex impedance is widely used across industrial, commercial, automotive, healthcare, and consumer markets, and can include applications such as proximity sensing, inductive transducers, metallurgy and corrosion detection, loudspeaker impedance, biomedical, virus detection, blood coagulation factor, and network impedance analysis. This session will cover the concepts, approaches and challenges of performing complex impedance measurements, and will present a system level solution for impedance conversion.
Weigh Scale Measurement: Most common industrial weigh-scale applications use a bridge-type load-cell sensor, with a voltage output that is directly proportional to the load weight placed on it. This session examines the basic parameters of a bridge-type load-cell sensor, such as the number of varying elements, impedance, excitation, sensitivity (mV/V), errors and drift. It will also discuss the various components of the signal conditioning chain and present solutions with high dynamic range.

This session combines the high-speed analog signal chain from RF to baseband with FPGA-based digital signal processing for wireless communications. Topics include the high-speed analog signal chain, direct conversion radio architecture, the high-speed data converter interface and FPGA-based digital signal processing for software defined radio. Demonstrations will use the latest generation Analog Devices high-speed data converters, RF and clocking devices, along with the Xilinx Zynq™-7000 SoC. Other topics of discussion will include the imperfections introduced by the modulator/demodulator with particular focus on the effect of temperature and frequency changes. In-factory and in-field algorithms will be examined that can reduce the effect of these imperfections with particular emphasis on the efficacy of in-factory set-and-forget algorithms.
This session will describe the various types of motors and help attendees develop a basic understanding of the differences between these and how to identify which is needed in particular applications. More detail will be provided around how to design isolated analog in high-end motor systems which require a FPGA. The FMCMotor1 hardware platform will be used to demonstrate rapid prototyping of motor control algorithms using Xilinx base platforms and the Mathworks Simulink® control system toolbox.
