This is an overview of the Analog Devices’ JESD204 Interface Framework, a system-level software package targeted at simplifying development by providing a performance optimized IP framework.
An Introduction to ADI’s Power components used in RF signal chains, with special treatment of high performance data converters, transceivers and PLL/VCOs.
An Introduction to ADI’s RF Switches and RF Attenuators including their key characteristics and how and where they should be used in the RF signal chain.
Digital isolation plays a key role in designing industrial motor control systems. This presentation takes you through why, where and how for isolation designs that optimize system performance while meeting the ever stringent safety and efficient standards. Analog Devices, Nicola O'Byrne at PCIM 2015
Isolation in gate drive is one critical area for designing efficient, safe and highly productive motor control systems. Learn how the latest ADI isolated gate drives can help you solve the design challenges. Analog Devices, Dara O'Sullivan PCIM 2015
When it comes to high performance signal chains, you need high performance power solutions. Noise sensitive
circuits such as analog-to-digital converters (ADCs), digital-to-analog converters (DACs), amplifiers, and phase
lock loops (PLLs)—as well as FPGAs—demand low noise power supplies that require specialized design
techniques. Engineers spend hours trying to figure out how to power these circuits without adding noise.
This presentation will focus on understanding various methods for not only approaching but meeting system
requirements. The session will introduce tested solutions and layout considerations that must be taken into
account when designing with switching regulators and low drop out (LDO) regulators.
This session provides insight into the operation of electric motor drive systems. Topics include electric motor operation and construction, motor control strategies, feedback sensors and circuits, power and isolation, and challenges of designing highly efficient motor control systems. A new high performance servo control FMC board will be introduced in the presentation, which provides an efficient motor control solution for different types of electric motors, addresses power and isolation challenges, and provides accurate measurement of motor feedback signals and increased control flexibility due to FPGA interfacing capabilities. The motor control hardware platform will be used to demonstrate rapid prototyping of motor control algorithms using Xilinx base platforms and the MathWorks development and simulation tools.
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 enormous amount of unproven solutions scattered across the Web. Signal Chain Designer is an intelligent selection and design tool that accesses verified product combinations and applications circuits, which can be customized or newly created according to user specifications. The Signal Chain Designer experience is supported by direct access to online EE design tools, evaluation hardware, software, documentation, and ADI Circuits from the Lab® reference circuits.
Sensors are the eyes, ears, and hands of electronic systems and 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. MEMS (microelectromechanical systems) sensors have opened up entire new areas and applications. In this session, the fundamental MEMS sensor concept of moving fingers that form a variable capacitor is covered, along with how it is turned into a usable motion signal. Adaptations for multiaccess sensing, rotational sensing, and even sound sensing, along with concepts of how these devices are tested and calibrated, are covered.
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 of the system requirements for both field instruments (sensors/actuators) and control room (analog input/output) modules, and demonstrates a typical I/O module configuration with HART® (highway addressable remote transducer) connectivity.
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. The demo board uses the latest generation of Analog Devices’ high speed data converters, RF, and clocking devices, along with the Xilinx Zynq-7000 SoC. Other topics of discussion 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 that reduce the effect of these imperfections, with particular emphasis on the efficacy of in-factory set-and-forget algorithms, are examined.
Instrumentation: Test and Measurement Methods and Solutions - VE2013Analog Devices, Inc.
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 better 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- vs. 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.
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 Σ-Δ 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.
