Demanding More From Analog Takes Work - The design engineer and the vendor must have a ...

Hmm... not sure how well various simulators do in this regard.... blogs message boards chat Field Programmable Analog & Gallium Arsenide Scott Elder, Senior Analog IC Design Consultant, 5/21/2013 Comment now 2 comments "Gallium Arsenide (GaAs) is the silicon of the future. Is and always will be." That was the humorous perspective circulating among analog technologists in the late 1980s. In a similar vein, I can't count the number of times I've had people ask me when will the world see a field programmable analog array (FPAA) -- the analog counterpart to the digital ... Most recent post, Scott Elder, 5/21/2013 12:05:54 PM Thanks for the comment, Derek. Let's hope others can expand the history.&n... Operations per Joule Brian Bailey, Independent Consultant, 5/20/2013 Comment now 4 comments It has been estimated that the human brain performs 3.6x1015 synaptic operations per second and, from blood flow and oxygen consumption, consumes 12W. That means it manages 3x1014 operations per Joule, yet it is made up of slow and noisy components. Most recent post, DEREK.KOONCE, 5/21/2013 12:08:00 PM Analog, in of itself, has infinite resolution. Yet I see it always ends up being... 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 8 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, DEREK.KOONCE, 5/21/2013 11:48:29 AM One other improvement thought is to think of the heat-sink capability of a thermocouple.... When Are You Done With Verification? Brian Bailey, Independent Consultant, 5/17/2013 Comment now 4 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, DEREK.KOONCE, 5/21/2013 11:39:24 AM I see true verification is to at least build up a circuit to ensure un-tested blocks... 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 ... Most recent post, analoging , 5/17/2013 6:53:53 PM SiGe is implemented more for its high-frequency benefits due to the mobility enhancement... 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. Most recent post, Michael Dunn, 5/16/2013 9:04:24 PM Love the constant-current transformers. Are there details of how they work? Some... 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 39 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 32 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.

Brad Albing on Litz Wire & Other Component Cleverness 5/21/2013 12:24:17 PM Re: It is not the harmonics!: Sawdust - Something to consider with regard to what signal [frequency] is being squared when you calculate the energy contained in the harmonics. In some cases, it's higher frequency bass or even mid-range signals that are clipping. Combine...

Of course, Barry is not recommending that you blow things up. If he did, you're right - his manager would probably have a talk with him... Brad Albing on Everything’s Better After the First Explosion 5/21/2013 12:08:00 PM Analog precision: Analog, in of itself, has infinite resolution. Yet I see it always ends up being digitized in some form to explain to people. And from a marketing perspective, touting 12 bits over 10 bits would make people want more. General public seem not...

Thanks for sharing. I have not heard of most of the companies listed. If someone is out there working on updating the semiconductor tree history, this would be a nice small chapter to add. DEREK.KOONCE on Field Programmable Analog & Gallium Arsenide 5/21/2013 11:48:29 AM Thermodynamics: One other improvement thought is to think of the heat-sink capability of a thermocouple. Though in most cases the thermocouple is very small compared to the object being measured, but if the masses are similar, then the thermocouple can act... DEREK.KOONCE on Thermocouple Nodules, Cold Junctions & Integration Opportunities 5/21/2013 11:39:24 AM Verification method: I see true verification is to at least build up a circuit to ensure un-tested blocks perform as expected. If it means a simple breadboard, then that would be a good solution. However, transferring from a breadboard to an IC can still have differences....

I got a chance to attend HP Lab seminar. Their presentation descries quantum information. HP has quantum science research lab. DaeJ on Operations per Joule 5/20/2013 10:28:21 PM modelling the transmission line: compared to using a co-axial cable having a CAT5 cable for connecting the 100BT line is much better due to the efficiency. But how difficult is it to model the transmission involving multi strands? amrutah on Litz Wire & Other Component Cleverness 5/20/2013 8:42:51 PM TCs are key: Having a good fundamental understanding of thermocouples is critical for work in clean rooms for the fabrication of microchips.
