Common-mode voltage for industrial transceivers
Signal Chain Basics 9/29/2015 1 comment
Most differential field bus technologies, like CAN and RS485, specify a parameter called common-mode voltage. Common-mode voltage refers to the range of bus input voltages, with respect to the transceiver’s ground, within which the transceiver maintains consistent input receiver thresholds.
Analog Devices Design Tools: ADIsimRF Part 3
Jonathan Harris 9/24/2015 2 comments
The ADIsimRF tool has many different calculation possibilities which are very nice to have on the hand. These can be useful when either in the lab collecting data or when working on a report in your office. The tool outputs are great to double check experimental results or to set expectations when about to take data.

Sanjaya Maniktala shared this life-changing and life-saving story with me and I thought our Planet Analog Audience would greatly benefit from his experience. I invite you, our readers, to please also share any mentor stories you may have with our audience as well.
Planet Analog Electronics book give-aways series
Steve Taranovich 9/21/2015 26 comments
I am planning a series of excellent electronics text book give-aways on Planet Analog beginning right now. I will have one new give-away every two weeks. The lucky winner will be the person who has the most worthy comment regarding who should receive the book and why.
What’s the big deal about Resonant?

Wireless power has made significant advancements in the last few years with many inductive technologies becoming mainstream and widely available – notably Qi and PowerMat products.
Why is my signal so distorted when I’m doing everything right (I think)?
Steve Taranovich 9/3/2015 1 comment
High speed converters have made many performance gains over the years, particularly in linearity, and therefore distortion. But to realize the performance, you need clean signal sources. Every once in a while I get an inquiry about having a clean setup, but still not meeting the distortion specifications
3 IoT-Based Myths about Analog Electronics
Steve Taranovich 9/2/2015 1 comment
The hype surrounding the Internet of Things (IoT) has been nothing short of monumental. The reality is that, by some estimates, only 4 percent of current IoT proposals will actually be of use once they come to fruition. Despite this disparity, the electronics industry is excited about those few products that will succeed and in turn be profitable
Feedback Circuits and Two-Port Blocks, Part 2: Feedback Circuit Misconceptions
Dennis Feucht 9/1/2015 Post a comment
Typical circuits textbooks tell us that there are four basic feedback topologies. The impression is given (if not stated) that a given feedback circuit will conform to one of these four topologies. This is misleading. One of the tasks of feedback analysis, it would seem, is to identify to which of the four basic topologies a given feedback circuit conforms. This article attempts to clarify and correct this misconception.
Analog circuits inherently have some inaccuracies; if these exceed the allowable specification, there are three general strategies to dealing with them.
Removing the vuvuzela narrow-band noise was presenting challenges to broadcast engineers
This article discusses how using a single synchronous buck controller can output the most common voltage rails, and accommodate a wide range of operating input voltages from 3V to 40V, and at a reasonable BOM cost.
This article explains how the latest-generation SiC FETs are ideally suited to new inverter designs with lower losses than IGBTs and proven robustness against short circuits, even at high temperatures and under repetitive stress
