ElectroMagnetic Pulse (EMP)---What's your Plan B?
Steve Taranovich 9/30/2018 12 comments
An EMP is a high intensity electromagnetic pulse having broad frequency spectrum covering from low frequencies to the VHF and UHF bands. EMP is still a serious threat to the electronic systems and communication systems.

Space screening for the standard space product offerings which include products such as ADCs, DACs, comparators, amplifiers, voltage references, switches, isolators, regulators, and attenuators
My Personal STEM Experiment

It’s hard to find viable, simple, tangible demonstrations of STEM-related concepts, but an old-fashioned Received Signal-Strength Indictor (RSSI) and TV provided one.
Is Graphene the Next Silicon?
Analog Angle 9/27/2018 1 comment
Like Silicon, single-atom sheets of Carbon, known as Graphene, can be the base material for diverse innovations across multiple disciplines and applications.
Creating sound for Electric Vehicle safety
Steve Taranovich 9/10/2018 3 comments
The air-polluting, carbon emitting standard liquid fuel combustion engine vehicles have an audible engine sound, even when traveling at low speeds. Pedestrians and other vehicle drivers recognize a moving vehicle via sight and sound coming from tires and other emitted noise when the vehicle may be out of sight.
Fully-Differential Amplifiers and the Leading Edge in Electronics
Dennis Feucht 9/7/2018 2 comments
Semiconductor companies have now had fully-differential amplifiers in their product lines for a few years, though these amplifiers have been in leading-edge electronics for decades. These diff-amps are differential not only at their input but also at their output, doubling output range.
Improving Phase Margin for Highly Reactive Rail-to-Rail Output Stage Impedances in Op Amp and Fully Differential Amplifier Applications
Michael Steffes 9/7/2018 Post a comment
Modern Rail-to-rail (R-R) output stage op amps, or fully differential amplifiers (FDAs), can sometimes get into a low phase margin condition for relatively simple circuits. Using the phase margin simulation test of Reference 1, a few simple external phase margin improvement methods will be shown. These tests and fixes are best done in simulation prior to board layout. Where the device model for a R-R output device is perhaps not including the higher frequency reactance, places for these tuning elements might be put into the board layout as a hedge against future stability problems.

I have always admired Medtronic’s technology. This is a company that helps improve the lives of so many people with their medical research and innovations
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
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.
