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.

Unfiltered Analog

Why is my signal so distorted when I’m doing everything right (I think)?


A Low Power Data Acquisition Solution for High Temperature Electronics Applications

A growing number of applications require data acquisition systems that must operate reliably at very high ambient environments, such as downhole oil and gas drilling, avionics, and automotive. This article presents a new reference design for high temperature data acquisition, characterized from room temperature to +175°C.

Analyzing, Optimizing, and Eliminating Integer Boundary Spurs in Phase-Locked Loops with VCOs at up to 13.6 GHz

A phase-locked loop (PLL) and voltage controlled oscillator (VCO) outputs an RF signal at a certain frequency, and ideally this signal would be the only signal present at the output. In reality, there are unwanted spurious signals and phase noise at the output. This article discusses the simulation and elimination of one of the more troublesome spurious signals— integer boundary spurs.


Voltage References Can Bite You, Too

Why does my voltage reference have nowhere near the accuracy guaranteed on the data sheet?
