Abstract
A resonator-based sensor and a sensing method thereof for sensing a change in a material that is subject to be sensed which include: generating an oscillation voltage signal by amplifying a current signal output from a resonator in accordance with a physical-chemical change of the material; and generating a gain control signal corresponding to a motional resistance and a clock signal corresponding to a resonant frequency of the resonator are provided.
