Choose ESD Protection Devices Sooner Rather than Later to Avoid Schedule Slippage
Chad Marak  
3/27/2015   1 comment
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.

. I received a very good reader question from my last blog post regarding the various parameters that are reported by the tool. Let’s take a look at an example and explore the parameters that are returned. In this example we will look at the AD9643-250.
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.

Don't “Brick” My Supply!
Steve Taranovich  
3/20/2015   Post a comment
In today’s connected world, software frequent-field updates are necessary to improve accuracy, or add on benefits or even fix bugs. If you like these updates to be invisible to you, you are going to love this idea - Instant updates that do not require your software to restart or cause any glitch in the power supply.
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.

Do Not Operate a Four-Switch Buck-Boost Converter in Buck-Boost Mode
Steve Taranovich  
3/18/2015   4 comments
A DC/DC converter converts an input voltage source to a desired voltage level. When the input voltage is higher than the desired output voltage, you need a buck converter. Conversely, when the input voltage is lower than the output voltage, you need a boost converter. In applications where the input voltage could be either higher or lower than the output voltage, what you need is a buck-boost converter.
Lacking Grand Answers? Look for the Best “Little” Answers
Steve Taranovich

Much time is spent discussing the need for more efficient use of limited energy resources, and with good reason. Energy demand continues to grow and the number of loads is predicted to climb exponentially as Internet of Things (IoT) deployment becomes real.
Seemingly Simple Circuits, Part 6: The Refined Current-Loop Converter Model
Dennis Feucht  
3/14/2015   4 comments
In this last part of a long article, we look at the final refinement for waveform-based modeling which is based on average switching-cycle current, not on peak or valley current values within the cycle. This is significant because the current of interest to us in power supply design is the average current. Power-supply ratings are based on it.

Steve Taranovich  
3/6/2015   3 comments
I am a strong believer in the STEM program for young children, but in this blog I want to address young girls in particular because the so-called “leaky” pipeline of engineering talent is seen predominantly at age 16, but typically the decision is made around age 14 or so.

Signal Chain Basics  
3/1/2015   Post a comment
A typical precision operational amplifier (op amp) may have a 1 MHz gain bandwidth product. Theoretically, you might expect RF signals that are in gigahertz to be attenuated to very small levels because they are far outside the amplifiers bandwidth.

Steve Taranovich  
2/25/2015   6 comments
There are 150 engineering schools in the state of Kerala with graduates leaving India for the allure of companies elsewhere in the world. The state of Kerala wants to keep these engineers right there in this region where they have graduated and is trying to create a “Silicon Valley” in India.
The Future of Custom ASICs
Steve Taranovich  
2/25/2015   3 comments
For decades, electronics product innovation has been incremental in nature, relying largely on the next generation of semiconductors to deliver performance improvement. For almost 50 years Moore’s Law has delivered 2x performance (power or cost) improvement in semiconductors every 18 months, outpacing any product or system level innovation cycle that could be achieved by even the most ambitious hardware teams. What has evolved is a “sit & wait” approach, to product innovation. However it is now clear that Moore’s law is broken, and the implications are profound for hardware designers.

Scott Deuty  
2/25/2015   Post a comment
You’re in a small company that needs to turn a product quick. Nobody in the company has any power supply design experience yet you need to drive LEDs from a universal (US and European) wall input voltage. What do you do?

Analog Angle  
2/10/2015   5 comments
Now systems are moving higher, with activity in the 5 GHz Wi-Fi band as well, due to crowding and interference issues at 2.4 GHz. Ironically, this at least partially due to the success of the cellular, Wi-Fi ad ISM initiatives at 2.4 GHz.

The MIT Age Lab recently worked with Monotype Imaging in an investigation of effects of typeface on the demand of human-machine interactions during a simulated in-vehicle point-of-interest (POI) menu selection task. Their study showed that people could perform a menu selection task faster and with more accuracy depending upon the text type used as well as white text on a black background vs. the standard block text on a white background. Differences were clearly noted.
