Going Full Tilt
Ian Beavers 8/16/2016 Post a comment
I would like to improve the accuracy and repeatability of tilt measurements using the ADIS16209 inclinometer. Can I use several of these sensors in parallel to improve the accuracy?
More to Microphones than MEMS

MEMS-based microphones are way ahead of traditional electromechanical microphones in unit volume; the classic designs still have their unique roles—but for how long?
Jupiter: The IC Danger Zone, Part 1
Kristen Villemez 8/10/2016 7 comments
There are many things which engineers at NASA, Space X, and at a semiconductor company like ADI must consider when developing products for use in space that anyone else wouldn’t have to worry about for earth-bound applications, most notably of which is radiation (of course unless you’re working on a nuclear power plant).

There is a plethora of devices aimed at very narrow markets. If you aren’t in that market you will never use one of those devices
Go ASIC for Analog?

Analog ASICs offer an alternative that deserves serious consideration, despite the huge number of excellent, off-the-shelf analog ICs.
NASA Juno electronics study Jupiter: Gravity Science Experiment
Steve Taranovich 7/19/2016 Post a comment
The Juno spacecraft now orbiting Jupiter has a suite of science instruments which will investigate the existence of a possible solid planetary core, map Jupiter’s intense magnetic field, measure the amount of water and ammonia in the deep atmosphere, and observe the planet’s auroras
Short notes about lightning: Part 1
Victor Lorenzo 7/18/2016 3 comments
For engineers and technicians, the event of changing occupation tends to come associated with the challenge of diving into new knowledge areas. Entering into the lightning research and protection world is one remarkable example.
Virtual Eval Through the Eyes of an ADC, Part 2
Jonathan Harris 7/15/2016 Post a comment
Now that we’ve had a chance to learn a bit about the tool we will take a look at using Virtual Eval to predict the performance of the AD9680-500 which has integrated digital downconverters (DDCs) and will compare simulated data to measured data.
Common-Base Bypassing and How It Affects CB Frequency Response
Dennis Feucht 7/8/2016 4 comments
The common-base (CB) BJT configuration is the second stage of cascode amplifiers. It is useful as a voltage translator to the high side of an amplifier with a large voltage range. This article addresses the question of how the RB, CB combination at the base node affects the frequency response.
Active Signal Characterization
Steven LeBoeuf, Ph.D. 7/8/2016 Post a comment
The accuracy of biometric wearables continues to get a great deal of attention, particularly related to the accuracy of optical heart rate monitors in consumer wearable devices today. There are many aspects to answering that question, but this post will focus on one of the most important aspects known as “active signal characterization”.

You think that rectification of a signal for power is a trivial matter. Beware, some people think they know, but what they know is dangerous. And that’s without hidden gotchas.

The NASA spacecraft, Juno, is about to complete its 1.8 billion mile journey to Jupiter and go into orbit around the giant planet on July 4.
Is AI biased?
Steve Taranovich 6/28/2016 4 comments
The “I” in Artificial Intelligence (AI) relies on inputs from the human beings that create it and teach it. Crawford says that Sexism, racism and other forms of discrimination are being built into the machine-learning algorithms that underlie the technology behind many “intelligent” systems that shape how we are categorized and advertised to.
Virtual Eval Through the Eyes of an ADC
Jonathan Harris 6/21/2016 2 comments
As I mentioned in my last blog I would like to take some time in this blog to introduce you to the new online simulator tool offered by Analog Devices called Virtual Eval.
Quiz questions published in EDN in 1985 and 1986 are still relevant today. Jim may be gone, but the analog gremlins live on.
Characterize the noise spectral density (NSD) of an LDO, otherwise known as a low dropout voltage regulator.
Lightning protection strategies gain a safety boost when complemented with storm tracking and prediction. There existing relation between the formation of electrostatically charged clouds and the occurrence of lightning can be used for improving safety and thunderstorms prediction accuracy.
The Author Explains Why Another Analog Circuits Book
Approximately 80 percent of total energy consumed by trains is for traction, and this energy is generally given off as waste heat as the train decelerates into a station.
