Measuring LDO Line Regulation for a Novice
Jonathan Harris 10/28/2016 Post a comment
A device going into space must be much more rigorously evaluated than a device going into a commercial product. Hence the need to do a good deal more characterization and ‘proving out’ of the device to make sure that it will endure the harsh environment in space as well as the long lifetimes required.
The LED Interior Lighting Craze, Part 2

In this this second part of LED Lighting Craze series, we focus on reliability. I found some interesting information on LED reliability for the components as well as the lights as a whole.
SOA, Watts Up, Transistor?: A Mystery of Self-Destructing MOSFETs

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?’
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
Ambulatory applications: Connected automobiles

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

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, NASA mathematician and scientist

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 6 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).
These days, I often code design equations for filter circuits directly into sequences of Excel cells
The introduction of the solar boat is necessary to preserve our planet, which is mainly covered by water; the autonomous drive option is a pleasant alternative
Leading up to APEC have been a slew of new introductions by various suppliers. I wanted to highlight some of that here on Planet Analog for your information
Could a 16-bit SAR converter application reach a dynamic range of 125 dB at 600 kSPS?
My ‘gut feel’ as an Electronics Engineer tells me that the need for more adequate and intensive pilot training is a strong possibility
