The analog shutdown on midnight Friday and subsequent frequency shuffle of digital broadcasts left this San Francisco Bay Area viewer pleasantly surprised.

The Digital TV switch was good for me

The Digital TV switch this weekend went smoothly in my San Francisco Bay Area home, more smoothly than I had anticipated. Admittedly, I spent lots of time, effort, and money getting ready for it—besides the converter boxes, I needed a new antenna, and my husband had to go up on the roof and replace our antenna twice before we got it right. Yeah, I lost one TV in the house—no antenna hookup for that third TV, and just too far from the transmitters to pick up a digital signal on rabbit ears.

But in spite of my pre-transition experience that foreshadowed problems with the analog shutdown—a dearth of English language stations and no American Idol viewing next season—we now have most of the channels we had before, plus a few extra, including a sports channel that has made it more difficult to pry certain family members off the couch.

The difference? Most stations in the San Francisco Bay Area changed their digital channels this weekend, in most cases to a much lower UHF or even to a VHF frequency. My understanding is that these new frequencies are somewhat less subject to attenuation, and the difference seems to be enough to put me inside instead of outside the reception footprint. So it looks like analog shutdown, after all, isn’t going to mean a monthly cable television bill in my mailbox.

The San Francisco Bay Area transition reportedly went forward with few hitches. According to a memo from Valari Staab of KGO television, KGO was able to resolve 80 percent of people’s problems receiving its signal on the phone, but acknowledges that, because it is being allowed to operate with more power than others assigned to Channel 6 or 7, the high-VHF frequencies, and broadcasting from its old analog antenna positioned at the top of Sutro Tower, it is having less issues than its brethren around the country. I may lose KGO for a while after mid-July, when it moves daytime broadcasts to an auxiliary antenna while crews are working to put new digital antennas for other stations up high on the tower. That work is expected to be complete in October. Staab also reported that local Best Buys have been running low on antennas.

In the rest of the country, reports, so far, are that things went smoothly. The FCC received nearly 800,000 calls this weekend; Chicago took an early lead as the spot with the most trouble. Volunteers around the country, from firefighters to members of Best Buy’s Geek Squad were standing by to help people hook up their converters. I just tried to explain to my mother, long distance, how to rescan for channels. I was unsuccessful; I gave her the Best Buy hotline, though I doubt she’ll take advantage of it. Fortunately, two channels in her area didn’t switch frequencies, so she’ll have something to watch until my next visit.

It may be some time, if ever, before we really know how many folks around the country were unable to make the transition, who either had to start paying for cable or satellite or adapt to a life without TV, because they are in DTV dead zones.

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.
