by Noel O’Riordan and Tommy Mullane, S3 Semiconductors When you’re designing sensor node devices destined for the industrial internet of things (IIoT), chances are they need to be battery-powered. And given the number of these expected to be deployed, and their often-remote locations, changing or charging a battery frequently isn’t an option. Your device, therefore, needs […]
PM Champion to receive award for helping advance technology applications
Chad Spore, staff engineer, Enterprise Materials Engineering, John Deere Waterloo Works Drivetrain Operations, Waterloo, IA, has been selected to receive the Vanguard Award from the Metal Powder Industries Federation (MPIF). The award recognizes powder metallurgy (PM) industry champions from the end-user community whose long-time promotion of the technology has contributed to the expansion of powder […]
Early warning for EMC problems
Engineers who wait until the end of the design phase to check for unwanted electromagnetic emissions run the risk of incurring big delays. Bruce Rose | CUI Inc. One design activity often left to the end of a project is the verification a product meets electromagnetic compatibility (EMC) emissions requirements. Considering EMC compliance earlier in […]
How power supply efficiency has evolved
The latest DoE energy efficiency requirements won’t be the last. Here are a few of the changes in efficiency regulations the power supply industry can expect. Authored by Inventus Power As early as the 1990s studies showed that smaller external power supplies — such as those powering cell phone chargers, game boxes, cordless phones, and […]
RS-232 and related standards, Part 1
High-speed, high-performance “just plug and go” wired-communications interfaces such as Ethernet and USB are in wide use. In contrast, the technically ancient RS-232 standard and related standards seem like antique museum pieces with no design-in interest. However, that is a simplistic view of the reality. Although not necessarily the first choice or obvious choice in […]
Analog Devices, imec partner to create utlra-low power sensor devices for IoT
Imec, and Analog Devices, Inc. announced they have entered into a strategic research partnership to develop the next generation of Internet of Things (IoT) devices. With two initiatives already underway, imec and ADI aim to innovate devices that are not only low-power but that also come with largely improved—or completely new—sensing capabilities. The IoT continues […]

Attend this webinar to learn about: Fixed ISA allows customization for […]
Getting started in electronics: core equipment
by Spec This article gives a list of equipment and material needed to get started in electronics. The essential equipment needn’t be expensive. Where to do your electronics project At its most elementary, all you need is a board of some kind, a table, and a mains supply. You also need a suitable room, which […]
Current feedback amplifiers, Part 2
Part 1 of this FAQ look at the operation of the CFB op amp and compared it to the VFB op amp. Part 2 continues the discussion of these two op amp topologies and their characteristics. Q: How do you choose between VFB versus CFB? A: Today’s CFB and VFB amplifiers have comparable performance, but […]
Component Obsolescence: more than a case of “you might also like…”
I have faced the problems of component obsolescence from my very early experiences of electronics design. In some cases it can be trivial — a transistor being discontinued and a suitable alternative easy to find. However, that is not always the case. Even a simple transistor replacement could result in PCB changes being necessary if […]
