Goodbye analog, I'm going to miss you

Will tonight's analog shutdown go smoothly, or leave millions frustrated?

Goodbye analog, I'm going to miss you

This morning I turned on the little TV that sits on top of the file cabinet in my home office. I bought it soon after 9/11, and typically use it for breaking news and major events, like presidential inaugurations. It gets three slightly snowy channels through a $10 rabbit-eared antenna; the antenna cable that drops through the walls and out through the floor in the family room and bedroom doesn’t make it over to this side of the house. That’s been fine for my purposes—breaking news tends to be covered across the networks, so three channels (ABC, NBC, and PBS) have been plenty.

There’s no breaking news today, so ordinarily this TV would be dark. But I plan on leaving it on from now until it’s getting nothing but static (or something called nightlight service that simply tells me my television is analog and needs a converter) as my personal farewell to analog television.

Because sometime between now and midnight tonight, the vast majority of analog broadcasting in the United States will cease.  Only a few low-power stations will remain. And since no converter box is going to be able to pull a digital signal from this particular pair of rabbit ears, the next stop for this little Sharp cathode ray tube television is the recycling center, where I can only hope it’s treated kindly and doesn’t end up hurting recycling workers or the environment.

I’ve got two other TVs in the house already hooked up to converter boxes, and a giant new antenna on the roof that enables those converter boxes to pull in a reasonable number of channels. But to date I mostly leave the converters turned off, since many of my favorite channels are, so far, only receivable on analog. That may change; along with analog shutdown comes the great frequency scramble, meaning channels I don’t get today, I might get tomorrow. Or not.

 

So tomorrow morning I’ll go over to those two TVs, turn on the converter boxes, and rescan for channels. I’ll have my fingers crossed, because here in the San Francisco Bay Area reception is spotty, and no one can really predict whether or not I’ll be have access to anywhere near the same menu of digital channels that I had in an analog world.

I doubt I’ll be the only one with my fingers crossed. Local broadcasters will be hoping not to lose viewers—and not to frustrate so many that their phone lines will be ringing off the hook come Saturday. The FCC will be hoping that they won’t be inundated by complaints, but they’ll have 4000 operators on call just in case. President Obama will be hoping that the transition goes smoothly, justifying the delay from the original date-certain of February 17th.

And in the next few weeks, we will see, because at this point, we just don’t know. As of last week, according to research firm Smith Geiger LLC, one out of eight folks who get their television over-the-air had yet to attempt hook up a converter box or digital television—Neilson estimates the number as just short of 3 million people. And that doesn’t count folks like me, who hooked it all up but still relies on analog for most of our TV watching.

So we will see if folks are thrilled with their new digital picture, or frustrated by their inability to receive anything at all without paying for cable or satellite. We’ll see what housebound elderly will do without baseball games to watch next week—I’m thinking of my 90-plus year old aunt and an 80-something former neighbor for whom snowy baseball games on ancient TVs provided constant companionship. I do hope it goes smoothly, that I—and every other over-the-air TV watcher in the country—is thrilled with the vast array of crystal clear channels and new wireless services that have been the promise of the digital transition. But we will see.

3D-Stacked CMOS Takes Moore’s Law to New Heights

When transistors can’t get any smaller, the only direction is up

Perhaps the most far-reaching technological achievement over the last 50 years has been the steady march toward ever smaller transistors, fitting them more tightly together, and reducing their power consumption. And yet, ever since the two of us started our careers at Intel more than 20 years ago, we’ve been hearing the alarms that the descent into the infinitesimal was about to end. Yet year after year, brilliant new innovations continue to propel the semiconductor industry further.

Along this journey, we engineers had to change the transistor’s architecture as we continued to scale down area and power consumption while boosting performance. The “planar” transistor designs that took us through the last half of the 20th century gave way to 3D fin-shaped devices by the first half of the 2010s. Now, these too have an end date in sight, with a new gate-all-around (GAA) structure rolling into production soon. But we have to look even further ahead because our ability to scale down even this new transistor architecture, which we call RibbonFET, has its limits.
