Kalman or FIR Filter for my IMU?
Ian Beavers  
3/30/2016   5 comments
In configuring my Inertial Measurement Unit (IMU) for post-filtering of the data after the sensor, I see options for both a decimation FIR filter and also a Kalman filter. Which one is best for my application?
The Drone Dilemma, Part 6: Drone Racing and Yet Another Acronym-- FPV
Scott Deuty  
3/30/2016   3 comments
It’s finally time to have a fun blog on drones. Whereas the first five blogs were more about the restrictions of drones, this blog addresses the fun sport of drone racing. For the most part, we dodge the restrictions. Like anything associated with drones, restrictions are leaking into drone racing

The basic principle of the working of the thermic diode is to use the difference in heat between two electrodes to move the electrons in a preferred direction
The stabilization of a big tower building: The electronics applied to the simulation of atmospheric factors
Busy Blogger

Big cities are fast growing and a large amount of persons are expected to live in big buildings; to ensure the capability of hosting a large number of persons, the buildings are developing in a vertical direction, thus big towers are the preferred solution to satisfy the requirement
When it Comes to Naming, Engineers Have No Lack of Creativity

I got the idea for this story while visiting the home of a friend recently. They had a small dog that liked to run in circles. As a result, it was named Google for the spinning arrow that pops up during the annoying buffering.
Top 10 must-have innovations for power designers from APEC 2016

In this slideshow, I will be providing power designers with, what I consider, the top 10 new innovative products and architectures announced at APEC 2016.
Phase noise cancellation in high-speed data converter systems
Signal Chain Basics  
3/20/2016   Post a comment
Clock phase noise or jitter (which is phase noise integrated across offset frequency) is a significant concern for high-speed data converter systems, and in some cases it can limit system performance
How to use slew-rate control for EMI reduction
Steve Taranovich  
3/20/2016   2 comments
Many industrial and automotive applications use the synchronous buck converter power-supply topology; these applications also require low conducted and radiated emissions to ensure that the power supply does not interfere with other equipment sharing the same bus
Capacitance sensing reveals more than just the obvious
Analog Angle

Using capacitance to count bees in a hive may seem "way out there," but it’s practical when combined with careful consideration of correction and calibrations factors plus empirical data.
How to extend a controller’s output-voltage range
Steve Taranovich  
3/18/2016   Post a comment
In this post, I’ll describe how to design a power supply using the LM5140-Q1 for industrial applications with a 24V output supplying 3A of load current.
Not Quite Darwin’s Theory of Evolution
Ken Coffman  
3/16/2016   3 comments
It strikes me there is natural evolution happening before our very eyes. What was analog, is becoming digital. For the next step, there are already signs that the digital is becoming software. There’s the well-trodden path: analog becomes digital, digital becomes software.
ADC Digital Downconverter: Decimation Filters and ADC Aliasing, Part 2
Jonathan Harris  
3/15/2016   4 comments
We will continue looking at the AD9680 as an example just as we did in part 1. Similar to the real mode operation of the DDC the normalized decimation filter responses are the same regardless of speed grade.
Keeping it simple still a good idea, for both problem and solution

Engineers know that keeping a design simple is a good idea; this assistive cane for the visually impaired reinforces that often-forgotten or ignored principle.
The Birth and Journey of the Ribbon Microphone
Steve Taranovich  
3/13/2016   2 comments
The year was 1924 when Dr. Walter H. Schottky and Erwin Gerlach co-invented the ribbon microphone. The design was made up of a very fine ribbon suspended in a magnetic field that could generate electric signals.
Seemingly Simple Circuits, User-Proof External Supplies: Circuit 3: The Two-BJT Current-Limited Supply
Dennis Feucht  
3/12/2016   4 comments
The improved one-BJT current-limiting supply is not much different than the primitive circuit, though its one additional resistor does change the circuit behavior
I-Sport: How smart shoes powered by smart integrated electronic devices can enhance our sport activities

Can electronic systems effectively improve your athletic skills, whether you’re a professional or a passionate runner? To try to answer to this question, let’s look at this recently introduced solution.
Slideshow: Medical Prostheses Marvels
Steve Taranovich  
3/10/2016   Post a comment
Engineering advances in the field of surgical amputation and the art and science/technology of designing artificial limbs have made it possible for persons who have lost a limb to receive a prosthesis that is able to function efficiently while looking like the original.

We are ready to have another great book give-away for next week. This time it will be to the Millennials
Why drive your car to work when you can fly it?
Steve Taranovich

I know that heavy traffic, car fender benders, bad weather on major highways going to and from work or stores can be frustrating
Google car accident: What does this mean for autonomous vehicles?

On Valentine’s Day this year, in Mountainview, CA (Where Google’s Global HQ resides), Google’s autonomous test car in that area had a minor fender-bender.
Seemingly Simple Circuits, User-Proof External Supplies: Circuit 2, The Improved One-BJT Current Limiter
Dennis Feucht  
3/1/2016   7 comments
Ordinary power supply design includes current limiting as a protection feature. In product design, this is usually sufficient in that the engineer decides the loads on the supply by design. However, in some applications a supply must be brought outside the box where it enters the realm of the user.
eGaN Technology Reliability and Physics of Failure Blog #1
Alex Lidow  
3/1/2016   Post a comment
In this first installment and the next, we will look at the field experience from the past six years of GaN transistors use in a variety of applications from vehicle headlamps to medical systems to 4G/LTE telecom systems. Diving into the failure of each and every part leads to some valuable lessons learned.
Valencell: The heart matters but the ear wins out in the final analysis

A good high-quality PPG signal is absolutely critical to proper heart rate accuracy measurements as well as many other biometrics parameters that are important to monitor, such as breathing rate, cardiac efficiency, blood pressure, and other important bodily parameters.
