AM Radio: The Beat Goes On (for a Little Bit Longer)
Analog Angle 2/27/2013 20 comments
AM broadcast radio has fallen on hard times. But before we dismiss it as a relic, let's do two things: Recognize how many of today's advances in electronics were driven by basic radio, and also admit that it is a model of channel simplicity and audience scalability.
Choosing & Using Bypass Capacitors
Brad Albing 2/27/2013 15 comments
Why do you need to use bypass capacitors in your circuit? What happens if you don't or you size them wrong or use the wrong composition? Do you want to find out the hard way?
Applying Duty-Cycle Control to Save Power
Martin Tomasz 2/25/2013 3 comments
For extremely low-power applications, a new approach is needed to conserve power. Rather than use conventional digital clock or timer techniques, a low-power analog timer is often good enough.
What Makes a Great Analog IC?
Analog Angle 2/22/2013 11 comments
There are many good analog ICs released each year, and some very good ones, but there are only a few great ones that make engineers go "wow" and achieve long viable design-in life as well. What are the ways for a product to achieve such status?
Don’t Bet Against Analog

Analog continues to be part of our lives because our lives and our experiences are and always will be analog in nature.
Enabling Analog Integration
Charles Razzell 2/15/2013 12 comments
What does it take to produce integrated analog devices? Is it just knowledge, or does attitude have an impact on the results? And what exactly constitutes an integrated analog device? Is it permissible to have any digital content?

With proper engineering, integrated analog devices will save you time (and money). Consider all facets of the design before making a decision.
Innovation Pays It Forward
James Niemann 2/12/2013 6 comments
The design work you do often has far reaching consequences. It can do good far beyond your lab bench and your shipping dock.
When Engineers Are a Little Too Smart for Themselves
Analog Angle 2/7/2013 5 comments
A good designer not only does a careful and thorough job, but also is careful not to count on subtle, non-guaranteed performance aspects of the circuit components -- which may change in a part redesign or in a change of vendors.
Questions About Analog? Step Right Up
Brad Albing 2/4/2013 5 comments
For the newbie, there are going to be plenty of questions about analog circuit design. To have any chance of success in your design work, you need to know what your fellow engineers are talking about and what they aren't telling you.
(Under)standing Your Ground
Analog Angle 2/4/2013 7 comments
It's OK to be less than precise when you use words such as "ground," but be careful that you don't forget that ground means a real connection to the Earth. Increasingly, that is not the case in many of today's product designs.
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
