Thanks to sensors, this zone is widening. Most recent post, D Feucht, 5/18/2013 6:45:20 PM "I am wondering how much finer wire provides the better performance in above application." The... When Are You Done With Verification? Brian Bailey, Independent Consultant, 5/17/2013 Comment now 2 comments In the everyday world that we live in, there is a common saying that says, "Measure twice, cut once". Clearly this is trying to stress the importance of checking things before you take action and that if you are sloppy with the measurement, then it can lead to expensive mistakes. Most recent post, Brian Bailey, 5/18/2013 1:04:04 PM I am not sure I understand the connection between outsourcing of manufacturing and... When the Going Gets Tough... Brian Bailey, Independent Consultant, 5/16/2013 Comment now 3 comments Moore's Law has been driving digital integration for a few decades, and it provides a circular reinforcement. Being able to create smaller devices means that more can be placed on a die. This provides added functionality, decreases costs per device, and makes demand for the end product larger. This spurs another round of integration and geometry reduction. Most recent post, Brian Bailey, 5/16/2013 9:29:25 PM That is very true. The EDA industry has been so concerned about timing and area... (Dis)Integrating Power Consumption, Counterintuitively Len Sherman, Senior Scientist, Maxim Integrated, 5/16/2013 Comment now 7 comments The present mobile era may be best characterized by its unrelenting pressure to reduce power consumption. Each generation of consumer electronics must offer more functionality while maintaining or extending runtime. Initially, efficiency improvements were the Holy Grail, at least from a power management viewpoint, but the process of engineering ...

Crack Open One of These Books, Part 2 Brad Albing, Editor in Chief, 5/16/2013 Comment now 2 comments Following up on Part 1 of my look at some favorite engineering books -- which followed Bill Schweber's blog about cracking open a design book -- let's consider a few more that provided solid engineering information.

Prevent Your Next High-Flying Product Launch From Being Grounded Willie Chan, Sr. Product Marketing Engineer, Linear Technology, 5/16/2013 Comment now 1 Comment The widening gap between the 24V-to-28V intermediate bus commonly found in industrial, aerospace, and defense systems and the input supply voltages of modern digital processors presents design risk that could easily result in system failure, noxious smoke, or, even worse, a fire. Most recent post, eafpres, 5/16/2013 11:36:37 AM Hi Willie--interesting post and situation created by the evolution of voltage standards... The REAL Cost for a Custom IC Scott Elder, Senior Analog IC Design Consultant, 5/14/2013 Comment now 32 comments There have been lots of blogs and messages lately about designing a proprietary analog IC. I wrote a blog about doing it on the cheap for $3,000. Reid Wender posted a message about prototyping 200 parts using a reconfigurable IC for $10,000. Most recent post, Scott Elder, 5/17/2013 7:45:00 PM Thanks Akbar. It's very kind of you to help fill out the list of open source... Everything’s Better After the First Explosion Barry Harvey, Intersil Fellow, 5/13/2013 Comment now 29 comments I'd like to take a few minutes to address the fear of power circuits and the great relief of successfully repairing the first screw-up of a project. Here is an example. Most recent post, DaeJ, 5/18/2013 5:20:57 PM I am not sure high voltage circuit with transformer was tested it the... Crack Open One of These Books, Part 1 Brad Albing, Editor in Chief, 5/13/2013 Comment now 24 comments After Bill Schweber wrote about cracking open a design book in Go Offline & Crack Open a Design Book, I looked through my bookshelf and came up with a few design books that had influenced me, although, interestingly, were more manufacturers' data and applications books.

How a Poorly Designed 20W Amplifier Can Destroy a Speaker System Brad Albing, Editor in Chief, 5/10/2013 Comment now 8 comments Even though we publish new blogs daily from your intrepid editor and from a number of well-known writers, sometimes it's good to have a look back at some of our well-received articles from the recent past. Here is one that discusses the consequences of driving a solid state amplifier too hard. With no provisions to limit output power gracefully, turning ...

Cupcake IC'ing Reid Wender, VP Marketing & Technical Sales, Triad Semiconductor, 5/10/2013 Comment now 9 comments I love where I work! I've worked at places where we've had cool perks like free lunch, a visiting masseuse, ping-pong, and foosball. Don't get me wrong, these things are great, but what I've come to really enjoy is working with great people.
