A Well-Chilled 750GHz Feasible Within 5 Years

Using superconducting materials cooled down to 5K a peak of 750GHz has already been reached. Just think about how far light goes within one clock cycle, and then tell me you aren't impressed." These low-temperature devices are made of niobium (a superconducting metal), and use something called Josephson junction devices, resulting in chips for which the article states "there are no known physical barriers to decreasing size by a factor of 10 and thus increasing speed by a factor of 10, using lithography to move from today's 3-m linewidth to 0.3 m."

      Actually, the resistance of a superconductor is estimated to be truly zero, because smaller and smaller measurements are made all the time and there has not been observed a finite convergence value. Also, you can have an eternal magnetic field by setting up a current loop in any superconducting ring, and the beauty of the thing is that you don't need to input energy once you set up the loop. Since it has no resistance a current loop in a superconductor would last forever.

  49. so what? by crgrace · · Score: 5
    Superconducting logic has been out for a VERY VERY long time. In fact, IBM burned tens of millions of dollars on the subject in the 1970s. The problems with superconductors are even WORSE than the problems with superfast III-V logic. UCSB has 70 GHz flip-flops made out of transferred-substrate heterojunction (III-V, Indium Phosphide and something else) transistors, but nobody thinks they will revolutionize computing, because they won't. So it is with superconducting logic.

    There are two huge problems with superconducting logic that don't seem solvable in the near future. They are:

    1. Cost : These things are enormously expensive to manufacture and operate, and it is the economy of scale of CMOS techology which has enabled, more than anything, the current computing revolution. Do you have any idea how expensive coolant and the dewar to use it in are to get something to 5K? Even the so-called "high-temperature" superconductors have to be pretty damn cold to function; they just don't need to go so close to absolute-zero.

    2. Integration This is probably the killer. It will be extremely difficult to integrate many devices together. Even if myriad technical difficulties are overcome, the solution is not likely to be inexpensive, as CMOS technology is. For III-V semiconductors (which use much less exotic materials than superconductors), high defect rate, problems with lattic matching of the materials, and the lack of a high quality native oxide (like SiO2 in silicon) have made it impossible to achieve integration levels anywhere close to that achieved in silicon. Even GaAs, the most well-understood III-V semiconductor, can't be integrated to more than a few thousand devices. That's why we don't have 20 GHz GaAs microprosessors. And superconductors are even HARDER to deal with.

    In summary, even if researchers are able to overcome almost insurrmountable odds to find away to reliably integrate meaningful numbers of these devices on a single die, I think it is very unlikely they will be able to do it cheaply, which is just as important as being able to do it at all. Otherwise, this technology will be of interest only to the military.

    By the way, I know III-V semiconductors have a lot of very important uses, especially in optics and RF. It is a fact, however, that III-V logic is mainly of interest to the military and the space industry.

      wass,

      First, the converter is clocked at 12.8 GHz, which is very different from running at 12 GS/s. It is definately an oversampled converter, because they mention a digital decimation filter, but they don't give you the oversampling ratio. By oversampling, I mean the input is sampled higher than the Nyquist rate and noise shaped. Then, it is digitally filtered back down to Nyquist with significantly less quantization noise than you would have had without oversampling. A common oversampling ratio is 128 which would put the converter at 90 MHz signal bandwidth, which is quite high for an oversampled converter. I'm totally guessing on the oversampling ratio, though.

      As for the number of bits it can do per sampling, that is largely irrelevent in a communications context. What matters is the SNR. You can figure out the number of bits of linearity with the following equation: SNR = (6*B + 2) dB where B=the effective number of bits. In other words, if you have an SNR of 60 dB, you have just about 10 bits of accuracy. The reason accuracy is specified as an SNR rather than a number of bits is if the converter is nonlinear (as it always is in practice) then even if you have more bits of resolution, the additional bits are inaccurate and should be ignored. For example, if you have a so-called "12 bit" converter with an SNR of 63 dB, then although you have 4096 possible output codes, the uncertainty between them is enough that the lower 2 LSBs are garbage, and, although you have 12 bits of resolution, you only have 10 bits of accuracy. This is a common way for manufacturers to lie on data sheets. Keep in mind, though, there are situations where resolution is more important than accuracy (such as digital imaging) and you'd rather have a 12-bit / 10 bit accurate converter than a 10-bit / 10 bit accurate converter.

      Hope that cleared things up. If you have more questions, email me or reply to this post. I just love talking about data-converters!

  71. Whatever happened to GaAs CPUs by pjrc · · Score: 4
    In the early 90s, it was widely believed that GaAs transistors would replace good 'ole Si for microprocessors. They're a lot faster, after all.

    Well, several things happened:

    • Nobody figured out how to make reseasonalbe P-channel devices.
    • Small geometries were much harder, because III/V and II/VI type (more than one element) semiconductors suffer from a whole bunch of problems where, which in my limited understanding (I'm a circuits guy) are due to the wrong atom at a place in the crystal lattice, such as a Ga where and As should have been.
    • It's easy to take Silicon Dioxide (glass) for granted, until you try to figure out a good way to make insulators on other materials.
    • All the while, good ole Si kept getting better and better... not only faster, but higher densities. Today's CPU speed is as much a function of using lots of transistors as it is their speed. As more transistors were available, everyone invested a lot of research and thought into ways to use them to run code faster (superscaler architecture, branch prediction, out-of-order and speculative execution, etc)
    Now I've been watching the J-junction for several years now, though I know much less about how it really works that I ought to. I do know there's a big difference between a test device and processes that produce only thousands of them to being viable for a modern microprocessor. GaAs transistors are hugely popular for RF applications, where you only need a small number of them. Today nobody believes the world will eventually be overtaken by GaAs based microprocessors.

    It seems unlike the world will really be overtaken by J-Junction microprocessors, at least in our lifetimes. Maybe that's just wishful thinking, since I've got a lot of energy invested in transistors, and with a bit of luck that'll remain valuable for another 25 years... but then again, look what happened to all those guys how only knew about tubes!

    Anyways, the point is that there's a big difference between a small number of insanely fast test devices to a high density processor with all the other requisites to make a reasonable microprocessor.

    I've worked for 4 months at the National Research Council in Ottawa, Canada, and there's only one thing you can use to cool down to 5K: liquid helium.

    We used liquid helium to cool our experiment. Back in '93 in bulk it costs about $10 CDN per litre. And it evaporates instantly on contact with air. You need to use liquid nitrogen to make sure that the surfaces holding the liquid helium are cold enough so that the helium doesn't just completely evaporate on contact.

    I saw another post saying $20k to cool the machine. That might be the cost per month of operation. While super fast chips may be feasable, the most cost effective cold you're going to get is just from liquid nitrogen. I'd probably try to start from there as a benchmark.
