A self-oscillation circuit includes an oscillating unit, an amplifying unit, and a resonator. The oscillating unit is configured to self-oscillate. The amplifying unit is configured to amplify a frequency signal oscillated at the oscillating unit and to feed back the amplified frequency signal to the oscillating unit. The resonator is disposed in an oscillation loop that includes the oscillating unit and the amplifying unit. The resonator has a resonant frequency near an oscillation frequency of the oscillating unit and has a higher Q-value than a Q-value of the oscillating unit. |
