Interesting. I think more research is required before I join the bandwagon.

Graphene has so much outstanding features that makes it an excellent candidate besides silicon, especially when it comes to high frequency communications as Mr. Frank mentioned. There is a pretty good chance to see this new technology in the real market at least in some critical fields of communications where it'll show premium performance.

This is a very promising development, especially for high frequency comms and radar applications in the near term...and possibly for more general CMOS supplement or replacement in the long term. And yes, some performance figures would be nice to illustrate whether this is just cool, really cool, or revolutionary.

I am wondering what makes graphene IC technology so intriguing compared to CMOS IC? In case of mixer in the article, I don't see any performance figures highlighted aimed to outperform CMOS mixers, for instance, power, noise and etc.

If graphene didn't require such high temperatures to form, its development could go even faster.

This development is serious stuff for defining the post-silicon era. Having device demos is one thing, demonstrating graphene circuits is a whole other bowl of wax. Does this technology now have a better chance of displacing or augmenting pure silicon-based circuits in specific applications?

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
