| Outline of Final Research Achievements |
The purpose of this study is to develop novel high performance sensors based on frequency delta-sigma modulation (FDSM) scheme using a THz oscillator. The FDSM is a core of the analog-digital converters featuring wide frequency bandwidth as well as high resolution, wide dynamic range. This can be applied to high performance sensors when we use an oscillator whose oscillation frequency depends on external physical paramters. In this study, we demonstrated high performance microphone sensors based on a cavity resonator oscillator, and also proposed a novel application of such sensors, such as atomic force microscopes.
