Four Quick Steps to Production: Using Model-Based Design for Software-Defined Radio

Part 2 — Mode S Detection and Decoding Using MATLAB and Simulink

The series on model-based software-defined radio system design continues toward the ultimate objective of building a platform that will receive and decode the automatic dependent surveillance broadcast (ADS-B) transmissions from commercial aircraft. This month our designers analyze the Mode S Extended Squitter format used in ADS-B signal transmissions and demonstrate how to capture these Mode S signals with a receiver platform based on the AD9361 RF agile transceiver IC.

Using ESD Diodes as Voltage Clamps

When external overvoltage conditions are applied to an amplifier's input, ESD diodes are the last line of defense between the amplifier and the catastrophic damage that can result from electrical over stress. In this article our expert shows us how ESD cells are implemented in an amplifier device, discusses their characteristics, and explains how they can be used to improve the robustness of a design.

The Truth About Voltage Feedback Resistors

The stability of my fully differential and voltage feedback amplifiers seems highly impacted by the value of my feedback resistors—the RF/RG ratio is always correct, so what’s happening?


Four Quick Steps to Production: Using Model-Based Design for Software-Defined Radio

Part 1 — the Analog Devices/Xilinx SDR Rapid Prototyping Platform: Its Capabilities, Benefits, and Tools

This article series examines the advances in platforms and tools that allow developers to quickly simulate and prototype wireless radio systems while establishing and maintaining a deployable path to production. As a real-world walk-through of the process, the authors will design and prototype a wireless an SDR platform that receives and decodes ADS-B aircraft signals.

New Advances in Energy Harvesting Power Conversion

Today many power management integrated circuits are available that were specifically designed for use in energy harvesting applications. They enable systems to run with smaller harvesters or make energy harvesting solutions possible that could not have been designed a few years ago. This article looks at several energy harvesting applications and describes a high-efficiency DC-to-DC conversion and voltage regulation solution that solves energy harvesting challenges.
