| Outline of Final Research Achievements |
We developed the elemental technologies for synchronization phenomena using a crystal unit with mechanical vibrations, which is represented by an equivalent circuit of a MEMS resonator. Synchronization phenomena of a group of noisy, non-interacting quartz resonators and their behavior during coupling synchronization are analyzed from the resonance frequency characteristics. Recent advances in semiconductor technology have made it possible to obtain general-purpose MEMS resonators at a low cost. In the future, we will be able to shift to the construction of synchronization technology for MEMS resonators using this technology.

現在の半導体産業は、素子の微細化や回路技術の発展などにより進歩を遂げてきた。その中で、素子サイズの物理的限界や、除去が困難な雑音などの問題が生じ、従来と異なるアプローチが求められている。一方で生物は、雑音を積極的に情報処理に利用することが知られている。このような雑音を利用する情報処理機構の開拓が、半導体産業の現状を打破する新たなアプローチの一つになると考えられる。
