Experiments were conducted with eight 450-MHz surface acoustic wave (SAW) resonators which demonstrate that a resonator's 1/f noise depends approximately inversely on the active acoustic area of the device. This observation is consistent with a proposed theory that 1/f noise in acoustic resonators is caused by localized velocity or dimensional fluctuations.
使用八个450兆赫的表面声波(SAW)谐振器进行了实验,结果表明谐振器的1/f噪声大约反比于器件的有效声学面积。这一观察结果与一种提出的理论一致,该理论认为声学谐振器中的1/f噪声是由局部速度或尺寸波动引起的。
