Use MacGyver's Methods, Part 4
Vincent Biancomano 5/28/2014 1 comment
Now we'll step up to an example where you can simply gauge how a given design proposal might fare even before you apply the meat of the design equations.
Wearable Technology for Behavior Control
Steve Taranovich 5/21/2014 19 comments
The recent fitting of an alcohol-detecting band to a convicted binge drinker in the UK is a reminder of how the use of wearable electronics for behavior control is proceeding apace.
Matching in Analog Layout
Keith Sabine 5/20/2014 Post a comment
Analog circuits often use structures like differential pairs and current mirrors, where matching of device characteristics such as the threshold voltage Vt is important.
ADCs Within Embedded Systems
Brandt Braswell 5/15/2014 Post a comment
As the market for cost reduction increases in intensity, the pressure is mounting to integrate or embed more of the functions within complex integrated circuits.
Analog vs. Digital: The Power Struggle Continues!
Steve Taranovich 5/9/2014 8 comments
If you are a power supply design engineer or an EE or ASE who selects power solutions for your end-system, then there is no doubt you have stood at the crossroads and pondered the dilemma of whether to go analog or digital with your power train.

How to implement an exposure measurement subsystem that can be incorporated into a hand-held exposure meter and even embedded in the light control loop of a photographic flash gun.
Excel: Taken for Granted, Part 1
Aubrey Kagan 5/7/2014 22 comments
When I started my blogs on Excel, I launched straight into it without any mention of some of the simple features that you may or may not know. As I move on, I think perhaps I should cover some of these features.
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
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.
