MIT Researchers Develop Graphene-based Microchip That Can Operate At 1,000GHz
Researchers at MIT have developed a graphene-based microchip that can operate at 1,000GHz, a much higher speed that conventional silicon chips would ever dream of reaching. These ultra-fast microchips can improve the data transfer rate for cellphones, computers, or other electronic devices. When it was discovered in 2004, graphene was regarded as a material that could lead to many new applications and it seems like this form of pure carbon can contribute to manufacturing transistors and prototype devices. The MIT team of researchers developed a graphene chip that was supposed to act as a frequency multiplier which can input an electrical signal of a specified frequency and output an electrical signal with a multiplied frequency. MITs graphene-based microchip managed to double the frequency of the input electrical signal, and besides that, it offers several other advantages. Conventional frequency multipliers need many components, generate messy electrical signal which have to be filtered and they consume large amounts of power. Well, the graphene chip is based on one transistor, it doesnt produce a messy signal therefore it doesnt need filtering, and it doesnt need too much power. Posted by: Anonymoose 2009-03-26 |
