Most recent post, SteveTaranovich, 5/23/2013 12:23:51 PM A flip chip is a chip packaging technique in which the active area of the chip is... Did You Say 'Programmable Analog'? Bill Schweber, Engineer, Author, Editor, 5/23/2013 Comment now 1 Comment 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, Brad Albing, 5/23/2013 10:20:40 AM >>you have an array of analog functions and can configure their interconnect... Build or Buy? The Design Rules Remain the Same Vincent Biancomano, Contributing Editor, 5/22/2013 Comment now 1 Comment 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, Vishal Prajapati, 5/23/2013 7:09:09 AM This has been the debate for almost every one from SME to PSUs. Probably PSUs don't... An Instrument on a Chip? A Look Back Dennis Feucht, Electronics Engineer, 5/22/2013 Comment now 8 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, Brad Albing, 5/23/2013 10:13:25 AM I recall that blog. That was a nifty piece of test equipment, and a good example... SiC Power Inversion Chips for PV & EVs Brian Coppa, Director, Coppa Consulting, 5/21/2013 Comment now 1 Comment 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, Dirceu Rodrigues Jr, 5/22/2013 11:14:56 AM The first time I heard about an application for Silicon Carbide... 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 11 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, 5/23/2013 10:00:11 AM OK, so maybe we should say, "For all intents and purposes, analog has infinite r... 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... When Are You Done With Verification? Brian Bailey, Independent Consultant, 5/17/2013 Comment now 6 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, analoging , 5/21/2013 7:10:44 PM The point was focused on the increasing trend of outsourcing of fab production for... When the Going Gets Tough... Brian Bailey, Independent Consultant, 5/16/2013 Comment now 5 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, Dirceu Rodrigues Jr, 5/21/2013 5:14:16 PM Reduce resistances in the signal path, in order to minimize the Johnson...

Dirceu Rodrigues Jr on (Dis)Integrating Power Consumption, Counterintuitively 5/23/2013 10:41:03 AM Re: TCs are key: Yep - I knew that - but you're right - lots of folks get that one wrong. That'd be a good question to give on a job interview. Brad Albing on Thermocouple Nodules, Cold Junctions & Integration Opportunities 5/23/2013 10:38:10 AM Re: Thermodynamics: DK - that's related to Heisenberg, isn't it? Or maybe it's the observer effect. You can't measure something without changing what you thought you just measured. Brad Albing on Thermocouple Nodules, Cold Junctions & Integration Opportunities 5/23/2013 10:31:01 AM 3-D printing...: Hmm... 3-D printing an IC at your desk - that's actually not a bad idea. Probably not practical today, but maybe soon - and then you actually could make exactly the analog IC you need, even if you only need small quantities. Brad Albing on Field Programmable Analog & Gallium Arsenide 5/23/2013 10:27:28 AM Flip chip?: I've seen the term "flip chip" before, tho' have not had a good understanding of it. Can you explain what exactly is a flip chip? Brad Albing on 3D Stacking Offers New Path to Optimum Integrated Analog Performance 5/23/2013 10:20:40 AM Configrable analog arrays: >>you have an array of analog functions and can configure their interconnect topology and some operating parameters in a one-time setup...I suspect there are just too many compromises that the user has to make, and the cost/benefit ratio... Brad Albing on Did You Say 'Programmable Analog'? 5/23/2013 10:13:25 AM Re: integrated DMM: I recall that blog. That was a nifty piece of test equipment, and a good example of integrating lots of analog functionality into a small amount of real estate. Brad Albing on An Instrument on a Chip?

A Look Back 5/23/2013 10:10:15 AM Re: Home made analog intruments: DF - you could go back to the arrays with a bunch of pinouts, but I'd be concerned that, even for preliminary testing of a concept, the parasitics as you've mentioned might be troublesome. Brad Albing on An Instrument on a Chip? A Look Back 5/23/2013 10:00:11 AM Re: Analog precision: OK, so maybe we should say, "For all intents and purposes, analog has infinite resolution."
