东京工业大学和日本信息通信研究机构(NICT)开发出了可以使无线通信电路不再使用晶体振荡器的电路技术。使用的是可通过MEMS(微纳机电系统)技术等集成在芯片中的振子。现有的无线通信电路在提供RF(射频)信号基准频率的LO(局部振荡电路)中使用晶体振荡器。比如,发送数百MH~数GHz RF信号的LO由能够使 Tokyo Institute of Technology and Japan’s Information and Communication Research Agency (NICT) have developed circuit technologies that will eliminate the need for crystal oscillators in wireless communication circuits. Using vibrators integrated in the chip by MEMS (Micro-nano-Electro-Mechanical Systems) technology. Existing wireless communication circuits use a crystal oscillator in an LO (Local Oscillator) that provides a reference frequency of RF (Radio Frequency) signals. For example, the LO that sends hundreds of MH ~ several GHz RF signals is enabled
