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.
Book Review: Linear Circuit Transfer Functions
Dennis Feucht 6/21/2016 Post a comment
Circuits can often be compartmentalized into stages with only one or two reactances in each stage. These circuits can be formidable to analyze for engineers unaccustomed to using much math, yet Basso’s book presents higher-level circuit theorems or methods that reduce their apparent complexity.
Simple μ C-Based A/D Converters, Part 2: Σ -Δ
Dennis Feucht 6/14/2016 Post a comment
Microcontrollers (μCs) often contain a comparator that can implement a precise analog-to-digital (A/D) converter (ADC) with the addition of only an external resistor and capacitor. It is a charge-balancing or Σ- Δ
DVD Variation with Load Vector Delays
Raj Nair 6/14/2016 Post a comment
In the following experiment, we explore DVD variance with another aspect of PDN load currents. Here, we explore the temporal relationship between load vectors: time/phase delays between load maxima.
Simple μC-Based A/D Converters, Part 1

One useful dynamic application of μCs is as analog-to-digital converters (ADCs). ADCs over the years have gone from complete DVMs as instruments to embedded subsystems, to a few components. This two-part article presents some minimalist techniques for implementing μC-based ADCs.
Analog circuits inherently have some inaccuracies; if these exceed the allowable specification, there are three general strategies to dealing with them.
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
