Technology Available for Train Safety Right Now Could Have Saved Lives
Steve Taranovich  
5/15/2015   5 comments
In light of the Amtrak incident that killed 8 people and injured over 200, I have to complain that the US authorities should have expedited a technological solution that will be mandated at the end of 2015 to greatly improve safety on the rails.
Electric Vehicle Connector Design: More Than Meets The Eye
Paul Pickering  
5/15/2015   Post a comment
Electric vehicles have been around a long time – over 100 years, in fact. Interest flared during the 1973 Arab Oil Embargo, which led to Congressional action in 1976 authorizing the Energy Department to support R&D into EV and hybrid vehicles.
Storage-Backed Inverters Doing the Same as the Smart Grid
Steve Taranovich  
5/12/2015   2 comments
One of the challenges with solar energy has always been storage. Installations produce a great deal of electricity to support a home or business, only to send the excess power back to the grid.

MOSFETs Balancing High Value Supercapacitors Greater Than 1000 Farads
Robert L. Chao  
4/28/2015   1 comment
We have frequent input from our customers who are developing supercapacitor modules consisting of two or more cells stacked in series and who want to know how to utilize MOSFETs to balance leakage current. Several engineers had a misconception and dismissed low current MOSFETs because the charge and discharge current of the supercapacitor exceeded that of the MOSFET.

Moore’s Law Demise: Maybe It’s a Good Thing!
Steve Taranovich  
4/11/2015   6 comments
Moore’s Law will celebrate its 50th anniversary on April 19, 2015. Many say that the statement or theory has run its course due to the next moves toward 450 mm size wafers, extreme ultraviolet lithography (EUV) and 20 nm CMOS.
There's Nothing Simple about that Wire Loop
Analog Angle  
4/9/2015   3 comments
Even the simple wire loop, whether as a basic transformer, an RF inductor, or a toroidal transformer, has a reality that goes far beyond the first-order model we first use to describe it.
When Blueprints Were Really Blue: Is Engineering Becoming Less Satisfying?
Paul Pickering  
4/8/2015   10 comments
I graduated college in 1979 (yeah, I know.... makes me about 35, right?). Back then our college Comp Sci department had less processing power than a modern toaster. There was talk, probably apocryphal, of a PDP-11 somewhere in the building, but we in the Physics department cut our teeth on a PDP-8, which had less processing power than a modern slice of toast. Nonetheless, we made do, learning machine code, assembly language and FORTRAN, booting up the machine with a strip of paper tape and entering our programs via punched cards.
EMI Noise, Part 4: Box Level EMI Suppression
Edgardo Menendez  
4/7/2015   1 comment
So far, we have discussed board level EMI suppression solutions, which are necessary to meet EMC standards. However, they may not be sufficient for applications in which the enclosed system is either not immune to, or even emits, EMI. Applications like these — including medical, space, aerospace, and other mission critical systems — require box level EMI filtering
Can μCs Replace Analog Circuits?
Dennis Feucht  
4/7/2015   8 comments
The cult of DSPism believes that eventually there will be essentially no analog circuits, that all circuitry will be either digital, as microcontrollers (μCs), with mixed-technology ADCs and DACs. This article explores the possibilities and limitations on this viewpoint
Logic
Ken Coffman

Here’s something annoying about engineers and anarcho-reductive philosophers—our training and background in Boolean logic. We tend to be analytical, even when making routine decisions—like what to have for dinner.
ADC Input Resistance: A Question of Sampling
Kendall Castor-Perry  
4/1/2015   Post a comment
One of our field applications guys wanted to know the input resistance of one of our ADCs; a customer had asked him and couldn’t find the data. Like most integrated ADCs these days, this one (the SAR ADC in our PSoC 4 family of devices) has a switched-capacitor front end and, in the interests of maximum flexibility and minimum power consumption, we don’t fit an input buffer amplifier. We let you do that if you want, but sometimes people want to ‘go native’ and feed the ADC directly.
Make a Freezer Alarm Using a Power Op Amp with Zero Power Consumption
Steve Taranovich  
3/31/2015   6 comments
When your home’s deep freezer, full of food, experiences an AC power failure while you are out for an extended time, its contents can thaw out. If the AC power is then restored before you return home, the contents can re-freeze and you may never know that your food is spoiled. This has given rise over the years to a number of freezer-alarm circuits and methods to detect thaw and re-freeze.
5G: Where Are We Now?
Steve Taranovich  
3/31/2015   Post a comment
It seems like we just had LTE and LTE Advanced beginning deployment in base stations everywhere. In spite of that effort, there has been heavy discussion of early development ideas of the 5G next-gen architecture to meet the ever-growing demands of the cellular airwave capacity, speed and customer future needs.
When Developing New Silicon IP, Is First Pass Success Possible? Part 1
Brandt Braswell  
3/31/2015   Post a comment
If you have worked in the semiconductor industry for more than a few years I am sure you have heard senior leadership speak about the need for your integrated circuit designs to be first pass successes and not the typical two to three spins or more to reach the targeted performance. The question is this: Is first pass success feasible and should be expected? I do not want to stir up a hornets nest with my response but the answer to the question is that it depends. Depends on what you say? Well, the answer depends on several different interwoven complexities that can determine if first pass success is possible. I would like to explore some possible ways to answer this question. Furthermore, the complexity of this question increases when developing complex mixed signal IC’s.
Choose ESD Protection Devices Sooner Rather than Later to Avoid Schedule Slippage
Chad Marak  
3/27/2015   3 comments
Fortunately for circuit designers, a new tool is available that can simplify the process of identifying the ESD suppression device best suited to an application, which makes it far easier to incorporate circuit protection earlier in the board planning process.

Signal Chain Basics (Part 100): Rethinking System-Level Management with Subsystem Over-Current Detection and Monitoring
Signal Chain Basics  
3/24/2015   Post a comment
Managing system thermal performance is critical in today’s electronic systems if you are to maximize performance and the user experience. As systems grow more powerful, and in many cases smaller in size, managing the thermal profile has become an ever-increasing challenge. Monitoring the current provides a leading indicator to potential thermal issues.

The Preservation of Richard Feynman Through Homomorphic Filtering
Dennis Feucht  
3/20/2015   Post a comment
I never met Richard Feynman but I am glad to say that I played a small role in preserving what he had to say, especially stories about events in his past. I first encountered Feynman’s physics books when I was in college in the late ‘60s.
