Integrated Approach to SPI using Digital Isolator Technology - SPI is used for IC-to-IC communications. Unidirectional lines make it easy to isolate, but interrupts and in-band addressing for target devices are not supported, so extra isolated channels are usually required. Also, the clocking scheme links the bus speed to the propagation delay of the isolation. This webinar looks at new integrated SPI digital isolators that address these shortcomings.
Troubleshooting your SAR ADCs - This webcast discusses the three main areas of support circuitry associated with high-resolution SAR ADCs. The first part focuses on driving the reference, choosing passive and active components, noise contributions, and performance characteristics. Next, we discuss front-end support circuitry, properly driving the ADC, and overstress protection. We conclude by highlighting support tools for evaluating or prototyping with ADI converters.
High-performance GSPS Data Converters Improve RADAR & EW Architectures - In recent years, ADCs sampling at GSPS rates have been pushing the data conversion stage closer and closer to the antenna, but when analog bandwidths reach 1 to 2 GHz, the ac performance of ADCs may be limited by the linearity and noise spectral density. This webinar discusses the advantages of new GSPS converters and the impact on radar and electronic warfare systems.
Digital Potentiometers - Where and How to Use - Digital Potentiometers (digiPOTs) provide a convenient way to adjust the ac or dc voltage or current output of sensors, power supplies, or other devices that require some type of calibration. This webcast describes the advantages of using digital potentiometers in various applications and shows the main parameters to be considered when designing a circuit using a digital potentiometer.
Isolation in Ultra Low Power Applications - Advances in isolation technology have reduced the power consumption of digital isolators by orders of magnitude, enabling safety and convenience in low-power applications. This webcast looks at several designs that take advantage of quiescent currents less than 1 µA per channel, including 4-20 mA field instrumentation, telecom interfaces referenced to negative 42-V rails, and battery operated devices.
Developing Multiple-Input Multiple-Output (MIMO) Systems with the AD9361 - As software defined radio (SDR) and multiple-input multiple-output (MIMO) become more prevalent, there is a need for more channel diversity. This webcast will detail how to use multiple AD9361 RF agile transceivers to create an N×N MIMO system, as well as explore the available tradeoffs in the design. The AD9361 is a fully integrated 2×2 MIMO transceiver. Its programmability and wideband capability make it ideal for a broad range of transceiver applications.
The Spectrum of Current Sensing: From DC to Light - Current measurement is an essential part of sensor interface, control, power management, and communications. The span of current sensing is from picoamperes to kiloamperes, and from dc to gigahertz (or light, when using photodiodes). We will cover high power and motor control, 4–20 mA industrial communications, energy monitoring, photodiodes, isolation, and developing precision current sources. We will also show on-line tools for circuit design.
Designing Wideband Front-ends for GSPS Converters - As high-speed A/D converter technology improves, so does the need to resolve very high intermediate frequencies (IF) accurately at high-speeds. This poses two challenges: the converter design itself, and the front-end design that couples the signal content to the converter. This webcast will define wideband passive networks and highlight important specifications for choosing a transformer or balun.
Digital Filter Design for Integrated RF Transceivers - This webcast introduces how MATLAB from MathWorks can be used for complicated filter design in wireless SDR systems and components. We will create a model of the Analog Devices AD9361 and AD9364 RF transceivers, as integrated on the AD-FMCOMMS2-EBZ and AD-FMCOMMS4-EBZ SDR development platforms. We will use that model to design a filter for the internal FIR filters using the generated coefficients in an example system design.
An Overview of Spectroscopy Instrumentation Techniques, Applications and Signal Chains - Spectroscopy techniques form the basis for almost all light-based measurements in laboratory and analytical instrumentation. This webcast will start with the basics, show the theory of operation, and describe some typical spectroscopy signal chains. Next, we'll explain the challenges of the primary photodiode path and finish with a discussion of the auxiliary measurements that need to be considered in the component selection and end system design.
Integrated Software-Defined Radio on Zynq®-7000 All Programmable SoC -- This course introduces wireless communication system design on the new Avnet Zynq®-7000 All Programmable SoC/AD9361 Software-Defined Radio Evaluation Kit featuring Analog Devices AD9361 single-chip RF agile transceiver. An IEEE 802.11 receiver example will demonstrate system-level simulation using MATLAB® and Simulink® modeling and code generation tools from MathWorks. Using the Xilinx Vivado® Design Suite, the system will be implemented for production showing the receiver detecting 802.11 beacon frames in a stand-alone system running UBUNTU desktop Linux on Xilinx Zynq AP SoC. Presentations will alternate with instructor-led demos to illustrate coding techniques within MathWorks and Xilinx development tools for high-speed digital signal processing.
Partitioning and Design for Precision Data Acquisition Systems -- Acquired analog signals can be manipulated and processed by either the analog or digital portions of a system, for example, through filtering, multiplexing, and 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 alter the nature of the analysis without changing hardware.
