The Diamond Plot

My signal is within the instrumentation amplifier’s specified input voltage range, but the output seems saturated. What’s happening? Is the part broken?
How to Measure an Ultracapacitor’s State of Charge & State of Health
Mike Everett 6/25/2014 13 comments
The use of electrochemical energy storage in high-reliability applications, such as those supporting the critical societal needs for reduction in carbon dioxide emissions or stabilizing the aging power grid, generally requires either real-time direct knowledge or at the very least, predicated state of the health of the energy storage device.
IMS2014 – The Preparation
Jonathan Harris 6/23/2014 5 comments
Once again I thought I'd do a series of blogs on my experiences as an applications engineer for a major semiconductor company, Analog Devices, at International Microwave Symposium (IMS).

This is the first in a series of articles that will address the quickly evolving art and science of transmitting useful amounts of power without wires.
Excel-Optimizing Resistor Ratios, Part 1
Aubrey Kagan 6/10/2014 20 comments
I have often wondered whether the practice of using a ratio of two resistors to determine a particular output is a fundamental property of electronics or a concerted effort by designers.
ADC Power Supplies: Inputs
Jonathan Harris 6/2/2014 5 comments
We’ll start by taking a look at the power supply inputs of the ADC, what we typically use to supply power to the ADC, and some of the tradeoffs of the different methods.
There’s a further cool thing you can do with a spreadsheet that most SPICEs can’t. That’s to use the spreadsheet ‘solver’ functionality to adjust component values in the search for a better-fitting circuit – or even to find a set of component values for a circuit you can’t otherwise design.
Infineon MOSFETs have been embedded into PC boards by Schweizer Electronic AG
You now need to adjust component values to achieve some system goal, such as predefined frequency response or time behaviour, and there’s no closed method for working out those values.
As a member of the electronics design community, I am angry and disappointed with the recent deaths of 346 people due to the Boeing MAX 8 design
The theoretical advantages of GaN-based power transistors are now being realized in mainstream system designs. Power supplies for data centers and telecom switching racks are two application areas where GaN transistors show significant improvement in comparison to systems using best-in-class Silicon-based Superjunction devices.
