<p><P>PROBLEM TO BE SOLVED: To provide a resonator in which effects of stray capacitance with respect to output characteristics of the resonator can be reduced or excluded and which can be easily implemented. <P>SOLUTION: The resonator comprises an oscillating element 1 that can be activated with electrostatic power, and a first exciting electrode 2 and a second exciting electrode 3 of the oscillating element 1. An AC signal generator is connected to the first exciting electrode 2 and the second exciting electrode 3 and sends a first signal and a second signal, which have the same amplitude and inverse phases, to the first exciting electrode 2 and the second exciting electrode 3. A first DC voltage source 8 is connected to a third electrode 4, a second DC voltage source 9 is connected to a fourth electrode 5, and an additional electrode 6 is connected to the oscillating element 1 electrically. A signal representing vibration of the oscillating element 1 is provided by the additional electrode 6 formed by an anchoring point of the oscillating element 1 and is biased by a third DC voltage. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
