Help of new materials has become possible 1000GHz GHz CPU

Throughout the course of development of the computer industry, people are always in constant pursuit of higher performance, upgrade the processor operating frequency is the most simple and effective method. And we know that, CPU operating frequency is multiplied by the FSB frequency to come. Therefore, if the upgrade can increase the frequency space, it can multiply rapidly improve performance.

But the frequency of the upgrading is not arbitrary. Frequency signal generated by the multiplier, when the rising frequency, the output signal of the frequency noise will also increase the need for filtering. In addition, high frequency electrical energy consumption is also required is considerable. This is the CPU frequency to enhance access to a major breakthrough in the delay of important reasons.

But a few days ago, the United States Massachusetts Institute of Technology researchers made use of new materials multiplier, it is possible to break this restriction so that the processor work on a surprising frequency.

This material, called graphene ,2004 by British scientists have discovered. It is a perfect single-layer two-dimensional crystal of carbon atoms, all carbon atoms are in hexagonal array. Familiar to us in a sense on the carbon nanotubes can be seen as a rolled graphene volume. Since this material was found, the scientists all over the world to explore it in the fields of electronics, microprocessor industry.

Massachusetts Institute of Technology, Electronics Engineering and Computer Science Associate Professor, Department of Tomas Palacios has announced that he had used graphene material required only a single transistor frequency multiplier, be able to output high-frequency signal purity, while energy efficiency is also very high.

Tomas Palacios said that under the conditions of existing technologies, resulting in the frequency of 4,5 GHz and above have a very high degree of difficulty. Graphene frequency multiplier and allows the system to run at 500GHz to the scope of 1000GHz. Although the device is still in the laboratory stage, but in 2012 on the application is expected to achieve. Graphene frequency multiplier of the technical papers will be published in the May issue of "IEEE Electron Device Letters," on.
