TRANSISTOR IBM operates at frequencies of 350 GHz
On Monday, IBM introduced a new design of transistor circuits for wireless communication, which promises to provide sufficient power to create networks of the future that can change the way people use wireless networks at work and at home. The new design of the transistor based on silicon-germanium (SiGe) technology, will provide a three-fold increase in performance. Department of Microelectronics IBM tells in detail about the details of this design at the International Conference International Electron Devices Meeting (IEDM), to be held in December in San Francisco.
New IBM transistor operating frequency 350 GHz clock rate will allow communication chips approximately 150 GHz and the data rate of hundreds gigabits per second. This is enough to transmit, for example, high-quality video from the TV adapter on a high resolution screen. Clock rate, these chips will be four to five times faster than the fastest chips used today in wireless LANs and home networks, and the energy they consume about 90% less.
SiGe technology is the incorporation of germanium atoms in different sites of the crystal lattice of silicon. This facilitates the flow of electrons through a transistor that can be used to improve performance or save energy. The rest of the manufacturing process is different from the manufacturing process conventional silicon chip, which makes mass production of its relatively low cost. According to the IBM, the chips with a new 350-GHz transistor will start to appear in 2005-2006.
In June 2001, IBM introduced the transistor with an operating frequency of 210 GHz, and the chips based on it should be on the market at the end of the future or the beginning of 2004.
