155 billion cycles which is more than Bejing

IBM has been showing off its latest graphene transistor that can execute 155 billion cycles per second. It is about 50 percent faster than previous experimental transistors.

The new transistor has a cut-off frequency of 155GHz. The previous one could manage 100GHz  and it was shown off last year.

Top Big Blue boffin Yu-Ming Lin said that the research also shows that high-performance, graphene-based transistors can be produced at low cost using standard semiconductor manufacturing processes. In other words commercial production of graphene chips is not far away.

Graphene is a single-atom-thick layer of carbon atoms structured in a hexagonal honeycomb form. It could be used for high-performance RF (radio frequency) transistors.

Electrons move faster on graphene transistors than conventional transistors, which enables faster data transfers. Unfortunately they are not ideal for PCs yet, because they do not have the on-off ratio required for digital switching operations. But it is good at processing analog signals.

I made the correction in the headline to say 155 Billion cycles....to match the context of the article....

Ft of 155 GHz is on par with the very fastest GaAs transistors. If they can get the process down to where it’s as predictable as silicon, graphene is going places.

Yeah but since it uses carbon as its base, when it burps, the carbon dioxide that it spews into the world will promote more global warming eerrrr, climate change.
