Re: Integration & Power consumption
Actually (just to pursue that a little bit), you'd end up with something that looke like one of those cell phones (or even wireless residential phones) that was the size of a brick. Ah... what memories.

Re: Integration & Power consumption
David, never thought of it from that perspective - assembling a smart phone from mid-90s technology. And not just from the perspective of PCB square inches, but power draw.

Re: Integration & Power consumption
Fascinating!  This appears to be right on, and yet another reason we'll see more applicaitons, like distributed, energy harvesting sensors.  I also loved seeing old names on that graph, like Commodore 64.

 

You're absolutely right about RF energy consumption.  Here's a cool project...put together modern smart phone functionality with technologies circa 1995.  I wonder what that thing would look like, and how much power it would consume.

 

Many analog sensing functions add very little power consumption, so I see this trend continuing, especially as microcontrollers get embedded into highly integrated analog parts.  I haven't done an actual computation, it seems like you would want to somehow couple in analog functions, like battery charging, while aren't going to involve so many calculations, but greatly improve battery life when integrated and moved to switch mode.

Integration & Power consumption
Hi David--great thoughts.  A couple years ago McKinsey had an article that showed a trend of computations/kwh vs. time.  The trend was linear upwards with a log scale for the computations/kwh axis.  The article can be found here:

http://www.economist.com/blogs/dailychart/2011/10/computing-power

The line of reasoning was that what had been happening since 1945 (Eniac) was decreasing the power per flop and that was the real underlying trend, not size or density.

What I find interesting is deeper analog integration should conform to a trend like that as well; we have already seen wireless technologies rapidly dropping in power consumption.  As the sensing side (analog) becomes more integrated with the rest of the electronics, that should also help lower power/performance.  What do you think about analog integration vs. power consumption?

Smart grid & LED lighting; who will lead us from the darkness?
David - I personally have a strong interest in smart grid and LED lighting, so I'm quite intrigued (or I will be intrigued) as developments from the semiconductor manufacturers show up on the market. And yes, the creative guys will lead, so I'll expect amazing things from these folks with regard to integrated analog functions pertaining to LED lighting and smart grid. Should be exciting if they pull it off.

We hear a lot about this "crisis," but whether it exists and, if so, to what extent, may be an unanswerable question.
A popular ‘free’ method in a buck converter is DCR current sensing. It’s free in the sense that no added cost or power loss is added to the design, but these circuits are notoriously inaccurate, particularly when small, low-ESR inductors are used.
Night flash is that moment when your dream is so intense that you wake up from it. In particular, this blog will focus on the creative moments of night flash as well as other venues of creativity.
I tell the younger generation that they would never be able to search the web for answers, send a Tweet, use Facebook or look at a YouTube video without mathematical equations and Leonard Kleinrock, the Father of the Internet.
It's formal end-of-life for this astounding consumer product, whose social impact is acknowledged while the amazing engineering feat it embodies is usually glossed over.
