SOA, Watts Up, Transistor?: A Mystery of Self-Destructing MOSFETs
Ken Coffman  
10/18/2016   16 comments
In this case we have a circuit that worked well at one operating point, but reliably self-destructed at another operating point. The active load circuits were the same. The transistor power dissipation was the same. The engineer pulls out his hair and cries out to the heavens: ‘What is going on?’

In this part, we go to greater depths to look at TL431 dynamics. Adjust your air regulator for the deeper dive. What is seen in the data sheet plots of gain and output resistance for some manufacturers is at first hard to believe.

The LED Interior Lighting Craze, Part 1
Scott Deuty  
10/14/2016   Post a comment
I have been observing the LED lighting transition in buildings and homes for several years now and realized that there are a lot of subjects that pertain to engineering and in particular analog engineering. This first part is an introduction to the industry as it currently exists. I’m not set on future subjects however I will be discussing more on reliability and smart control. For now, I’ll introduce the initial subject

The penetration of technology in mobility solutions is increasing. But automated cars and connected cars are about more than just being technologies which are charming. Some of the solutions they are likely to offer in the future can be expected to change the lives of people at the grassroots level.

The advantages of cycling sport activity are well known: riding a bicycle allows the oxygenation of the blood of the rider. This type of aerobic training allows the rider to burn many calories, lose weight, and make the heart and the lungs stronger. The more frequently this sport activity is practiced, the more effective the positive results will be. Electronics technology is a perfect solution to make the cycling activity easier because, when an electric motor is integrated into the bike it produces a power proportional to the dynamic power produced by the biker.

Operate General Purpose I/O with Strong Security
Steve Taranovich  
10/6/2016   Post a comment
Embedded electronic authentication ensures that sub-systems, accessories and peripherals used with or within a piece of equipment are not counterfeit. Additionally, by employing electronic authentication, manufacturers can more fully control the usage and performance of their products. Depending on the application, electronic authentication helps to maintain product reliability, accuracy, safety, and security to protect an OEM’s R&D investment

Katherine Johnson, now a retired NASA research mathematician, was no stranger to geometry. She was the one who would calculate the trajectory of Alan Shepard's 1961 trip into space. This was America's first big step to putting a man on the moon
Vacuum tube computers: The WWII 1943 Colossus Mark I
Steve Taranovich  
10/1/2016   7 comments
I have always been interested in electronics engineering ingenuity used to solve “impossible” problems. One such problem was the task of deciphering the German Army’s most secret transmissions during WWII via a German teletype machine named Tunny (that’s what the British called tuna).
P Channel and N Channel MOSFETs in Switched Mode Power Supply Applications
Scott Deuty  
9/30/2016   Post a comment
MOSFETs have been the chosen transistor technology in most Switched Mode Power Supplies (SMPS) since the mid 1980’s. MOSFETs are used as the main switching transistor as well as to improve efficiency when used as gated rectifiers. In order to choose the best switch for power application this blog provides a comparison of P Channel and N Channel enhancement mode MOSFETs.

“Free” DCR Current Sensing Must Die
Ken Coffman  
9/23/2016   Post a comment
A popular ‘free’ method in a buck converter is DCR current sensing. It’s free in the sense that no added cost or power loss is added to the design, but these circuits are notoriously inaccurate, particularly when small, low-ESR inductors are used.

Signal Chain Basics #116: Combining signals for better performance
Signal Chain Basics  
9/13/2016   2 comments
When the phase noise performance is just not good enough, one possibility is to combine two or more signals that are in phase to generate a better phase noise signal. This concept applies to the scenario of combining two sides of a differential output to form a single-ended output or the combination of signals from two semiconductor chips of the same type and configuration.
Vaporware for the Internet of Things
Scott Elder  
9/13/2016   2 comments
For those who aren’t familiar with the term vaporware, it simply means hardware or software that is heavily promoted, but not for sale. Like any vapor, it exists only in air. This seems to be the case with narrow band Long Term Evolution (LTE) modems for the Internet of Things (IoT).

The world of automotive today buzzes with three words, electric cars, car sharing or licensing and autonomous cars. It is pretty interesting to see the way the world is shaping up to accommodate these trends and how these trends are actually shaping up because of the direction in which the human civilization is headed.
Power Integrity for IoT Components
Raj Nair  
9/6/2016   2 comments
A prevailing assumption in the industry, EDA in particular, is that IoT chips are less of a challenge. Technology and IP integrated are well known. The chips are not leading edge in the fabrication processes used. Tools that met the needs of prior fabrication processes hence suffice to meet the needs of IoT chips. It is just a matter of designing to the specific application
Using Excel as a Design Aid in Lookup Tables
Aubrey Kagan  
9/6/2016   Post a comment
It is no secret to my legions of followers (Hi, Mom!) that I enjoy working with Cypress’ PSoC architecture especially the PSoC4 and PSoC5 varieties. Let me state up front that this blog is far more about the usage of Excel than about the PSoC, so don’t tune out just yet. I have written quite a bit on the application of Microsoft Excel to different aspects of electronics, often, I hope, with some originality

A Boost for Automotive Start-Stop: Dual Use of EMC Components
Mike Donnelly  
8/30/2016   Post a comment
Automobile manufacturers are increasingly turning to start-stop systems to glean an extra 3% to 12%* of fuel economy out of conventional vehicles. With this approach, the Internal Combustion Engine (ICE) is turned off during idle periods, such as at traffic lights or in stop-and-go traffic, and then automatically restarted when the driver depresses the accelerator pedal
