That means it manages 3x1014 operations per Joule, yet it is made up of slow and noisy components.

Using ICs in the Land Beyond Their App-Notes Derek Koonce, Owner, DDK Interactive Consulting Services, 5/20/2013 Comment now Designing circuits is the fun part of engineering. And, as has been often noted here on Planet Analog, finding solutions to problems is what keeps an engineer employed. As an engineer, it is necessary to work with the parts available to meet design criteria. This sometimes necessitates using a part for a purpose for which it was not intended. Thermocouple Nodules, Cold Junctions & Integration Opportunities Dennis Feucht, Electronics Engineer, 5/17/2013 Comment now 7 comments When measurement instruments reach their specified performance limits, one comes to a gray zone separating reality from fantasy. Thanks to sensors, this zone is widening. Most recent post, analoging , 5/20/2013 8:42:51 PM Having a good fundamental understanding of thermocouples is critical for work in... When Are You Done With Verification? Brian Bailey, Independent Consultant, 5/17/2013 Comment now 3 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.

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.

The REAL Cost for a Custom IC Scott Elder, Senior Analog IC Design Consultant, 5/14/2013 Comment now 38 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.

Everything’s Better After the First Explosion Barry Harvey, Intersil Fellow, 5/13/2013 Comment now 31 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.
