Record Setting Silicon Resonator Reaches 4.51 GHz
bibekpaudel brings news that researchers from Cornell University have developed a very small silicon microresonator that vibrates at the highest frequency ever recorded for such a device: 4.51 GHz. Typical quartz-crystal oscillators, commonly used in electronics as clock signals, are about a millimeter wide and operate in the KHz - MHz range. The newly developed microresonator measures 8.5 micrometers long and 40 micrometers wide, making it ideal for use in smaller circuits and microprocessing. Quoting: “One of the advantages of silicon microresonators is that they can be integrated directly into microchips using conventional manufacturing techniques, making them cheaper to produce and easier to fabricate small. Also, multiple resonators of different frequencies could be put on the same chip, says Ville Kaajakari, an assistant professor of electrical engineering at Louisiana Tech University. In a cell phone, for example, high-frequency resonators could filter out interference from other sources of radio signals.”
