Abstract:
1. An oscillator comprising: a piezoelectric material configured to vibrate in a mode; a first inverting amplifier; a second inverting amplifier; a first output electrode configured to apply an output signal of the first inverting amplifier to the piezoelectric material; a second output electrode configured to apply an output signal of the second inverting amplifier to the piezoelectric material; a first input electrode configured to receive a voltage signal generated by the piezoelectric material and output the voltage signal to the first inverting amplifier; and a second input electrode configured to receive the voltage signal and output the voltage signal to the second inverting amplifier, wherein the first output electrode and the second output electrode are coupled to the piezoelectric material so that faces of the piezoelectric material move in opposite directions, and the first input electrode and the second input electrode are coupled to the piezoelectric material so that the voltage signals which are generated by the piezoelectric material and have opposite phases are input to the first input electrode and the second input electrode.
