One of the most fascinating aspects of many technologies is the way they transform the world in ways completely unanticipated by their developers.
Sensor Footprint Evolution: Does Size Matter?
Steve Barraclough  
7/25/2014   10 comments
Industry observers will not argue that the explosion in the adoption of motion sensors, principally accelerometers, was enabled by reducing the form factor to the point where the sensors could easily be integrated into mobile applications.
More on Measuring the State of Health and State of Charge of a Battery
Mike Everett

In an ultracapacitor, end of life does not arrive abruptly and without warning, as it may with batteries. An ultracapacitor will conceivably continue to operate until there is not enough energy left in the device when fully charged to do the job.

Here is the third of three short tech nuggets, by Rich Nowakowski from TI, before our “Ask the Experts” session on Wednesday, July 23, at 1:00 p.m. ET (10:00 a.m. PT).
The Internet of Things: Sensor Fusion (or Confusion?)
Jay Esfandyari  
7/22/2014   21 comments
What keeps the Internet of Things from becoming a tangled jumble of incoming data from various connected devices? And within a single device that feeds information into the IoT, how does sensor fusion work?
Supercaps Improve Engine Start Reliability for Wide Range of Transportation Uses
Steve Taranovich  
7/22/2014   Post a comment
Supercapacitor technology is gaining momentum for improving the reliability of engine starting, extending battery life, expanding temperature range, and reducing replacement costs.

How a Coffee Packaging Machine Educated Me
Aubrey Kagan  
7/18/2014   29 comments
One of my first projects was to design a control for a coffee packaging machine. It was in the late 70s and microprocessors were on everybody's lips, but few actually knew anything about them.
Just Add a Transistor: The 4-20 mA Current Loop
Kendall Castor-Perry  
7/17/2014   8 comments
The good old 4-20 mA loop. Originally just for analog signals, it is now often used with a superimposed AC communication layer called HART.
Signal Chain Basics #91: The Difference Between HBM & IEC 61000-4-2 ESD Immunity
Signal Chain Basics

Explaining the differences between the two most commonly applied ESD standards.
Stability Prognosis of Components During Dry Heat & Biased Humidity Testing & Application
Reiner W. Kuehl  
7/16/2014   Post a comment
This paper introduces a method for the prediction of electrical parameter changes due to aging.
Energy Harvesting for Wearables
Thomas Kail  
7/15/2014   23 comments
Wearable applications including smart watches, sport watches, fitness bands and more are growing in popularity, and so, too, is the demand for intelligent sensors to use in them. If analyst predictions are correct, the market is going nowhere but up in the coming years.
How Can Technology Help Improve the Prospect of a Longer Life?

A few examples where energy harvesting wireless technology enables seniors to live independently for as long as possible, by retaining their dignity and increasing their safety.
Balancing Multiple Supercapacitors: Customer Q&A for ALD Tech Support
Steve Taranovich  
7/11/2014   5 comments
As it often happens, when new technology is introduced to replace the traditional circuit design methodologies, designers have questions. This was the case when Advanced Linear Devices recently announced its Supercapacitor Auto Balancing MOSFET arrays.
Your Chance as an Audiophile to Weigh In on Radio History

Who's got a professional audio lab, the desire, and the time to inspect my files and make a determination, gratis?
Improving Analog Design Time
Keith Sabine  
7/9/2014   10 comments
Designers can estimate parasitics early in the design flow, at the RTL level, to see if they meet timing and power criteria. Thus design changes can be iterated relatively quickly until the design goals are met, with detailed layout following.
Parasitics & Capacitor Selection, Part 4A: Dissipation Factor
Chris Reynolds  
7/8/2014   Post a comment
This month, we'll look at dissipation factor, and we'll lay the groundwork for next month's blog about Q.
Parasitics & Capacitor Selection, Part 4B : Dissipation Factor
Chris Reynolds  
7/8/2014   1 comment
Since capacitance bridges measure capacitance using a small AC signal voltage, it is possible to measure DF simultaneously.
Interfacing to ADCs: Power Supplies, Part 1
Jonathan Harris  
7/7/2014   2 comments
Keeping the power supply inputs on separate domains can minimize crosstalk and make it much harder for noise to interfere with ADC performance.
When GND Isn’t GND, Single-Ended Circuits Become Differential

The system ground return, or GND, symbol is often taken for granted when drawing schematics.
Signal Chain Basics #90: Calculating Harmonic Distortion Frequencies in High-Speed Data Converters
Signal Chain Basics  
7/3/2014   4 comments
Data converters, which convert digital to analog signals and analog to digital signals, have different characteristics than purely analog circuits. One of the most common misunderstandings is the frequencies of distortion products in data converters.

Paolo Scalisi  
7/2/2014   7 comments
A “cookie” approach can be used to build a net of sensors that can give a lot of information to a central processor based on a set of microcontrollers, which can control a series of actuators to realize a really smart system.
