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


most recent messages 5/25/2013 4:40:41 PM SteveTaranovich I like the term "Digitally assisted analog". It conveys the fact that both have their strengths and when combined, they make a far superior process or function than they would indivdually. blogs message boards chat The Analog Brain Brian Bailey, Independent Consultant, 5/24/2013 Comment now 7 comments In my last blog, Operations per Joule, I talked about digital, analog, and the brain -- comparing the energy efficiency of each and questioning the approach we take to solve problems. Most recent post, SteveTaranovich, 5/25/2013 4:40:41 PM I like the term "Digitally assisted analog". It conveys the fact that both have... PIC (& Software) 1, Op-Amps 0 Doug Grant, Independent Consultant, 5/24/2013 Comment now 10 comments I have a current project that requires sensing an analog voltage, and turning on an LED when each of three thresholds is reached. The analog voltage relates to a detected RF power level (in the 50 to 100 watt range, at HF), and the whole circuit is powered by scavenging a little bit of the RF power and making some dc from it. I need about 100 of these ... Most recent post, Brad Albing, 5/24/2013 11:25:10 PM I sort of had that idea in mind - but not completely formed. You clarified it for... 3D Stacking Offers New Path to Optimum Integrated Analog Performance Steve Taranovich, Senior Technical Editor, EDN, 5/23/2013 Comment now 20 comments Designers, who need to build high performance real-time sensing systems, are greatly challenged since every building block in the system needs to be built with a technology that allows that building block to achieve its best performance. 3D stacking is emerging as an option to allow the integration of those heterogeneous blocks. Most recent post, Brad Albing, 5/24/2013 11:19:24 PM I recall the OPT101. I used that in a design a bunch of years ago. Did You Say 'Programmable Analog'? Bill Schweber, Engineer, Author, Editor, 5/23/2013 Comment now 10 comments Whenever I see a new product announcement saying an analog or mixed-signal component is "programmable," my first thought is simple: "in what way?" Often, it's not called out clearly or until the end of the press release. Most recent post, Dirceu Rodrigues Jr, 5/24/2013 7:56:57 PM "Do you welcome highly integrated, functionally targeted ICs? Or do you chafe at... Build or Buy? The Design Rules Remain the Same Vincent Biancomano, Contributing Editor, 5/22/2013 Comment now 4 comments The last time I visited the "build or buy" issue, a lot of small commercial engineering outfits were looking to the big companies for in-house support for their various products for the burgeoning wireless market. Most recent post, analoging , 5/24/2013 3:17:16 PM In some ways, ARM has a benefit from solely focusing on designing chips for its... An Instrument on a Chip? A Look Back Dennis Feucht, Electronics Engineer, 5/22/2013 Comment now 9 comments The story of analog integration in test instruments is long, storied, and rife with names renowned in the annals of analog design who innovated upon each others' design to realize the foundation of today's circuits. So what is the state of integration of the analog circuitry in test instruments? Measurement on a chip started long ago and continues ... Most recent post, analoging , 5/23/2013 4:06:49 PM Ahhh, those were the days...running manual multi-meter measurements and recording... SiC Power Inversion Chips for PV & EVs Brian Coppa, Director, Coppa Consulting, 5/21/2013 Comment now 2 comments Uncertainty hangs over the market for power devices made with the wide-bandgap semiconductor SiC (silicon carbide), due to uncertainty as to when EVs (electric vehicles) will adopt them for various applications under the hood, according to a recent study by analyst firm Yole Développement. Most recent post, analoging , 5/23/2013 3:39:15 PM Thanks for the comments. SiC has a lot riding on the future of electric cars- no... Field Programmable Analog & Gallium Arsenide Scott Elder, Senior Analog IC Design Consultant, 5/21/2013 Comment now 4 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, Brad Albing, 5/23/2013 10:31:01 AM Hmm... 3-D printing an IC at your desk - that's actually not a bad idea. Probably... Operations per Joule Brian Bailey, Independent Consultant, 5/20/2013 Comment now 17 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, Brad Albing, 5/24/2013 1:15:02 PM OK - that explanation makes good sense. Thanks. Using ICs in the Land Beyond Their App-Notes Derek Koonce, Owner, DDK Interactive Consulting Services, 5/20/2013 Comment now 7 comments 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. Most recent post, Vishal Prajapati, 5/23/2013 7:29:42 AM The basic circuit is exactly a Joule Thief. I have worked on this device with same... Thermocouple Nodules, Cold Junctions & Integration Opportunities Dennis Feucht, Electronics Engineer, 5/17/2013 Comment now 13 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, Brad Albing, 5/23/2013 10:41:03 AM Yep - I knew that - but you're right - lots of folks get that one wrong. That'd...

Brian Bailey on The Analog Brain 5/25/2013 8:36:33 AM View From A "Young'n": My day job is an analog / digital / RF custom integrated circuit engineer. I personally love the analog design side much, much more so than the digital side. By age measures, I was born around the time the horzontal output tube was replaced... Jonathan Jensen on Crack Open One of These Books, Part 2 5/25/2013 7:51:35 AM Another Viewpoint: I have been working for a custom ASIC design center for thirteen years now. Everything I have done has been customer driven - not academic. My employer fabricates and tests the ASICs as well. I have led many projects from idea stage (feasibility)...

The wife would cut me off for a few weeks. :-) RedDerek on The Analog Brain 5/24/2013 11:25:10 PM Re: The Path of Least Resistance: I sort of had that idea in mind - but not completely formed. You clarified it for me. It's sort of like using a DAC as an ADC by putting some additional cktry around it.
