An oscillating apparatus for outputting an oscillating signal includes a resonant circuit that generates the oscillating signal, an amplifier circuit that amplifies the oscillating signal generated by the resonant circuit, and feeds the amplified oscillating signal back to the resonant circuit, and an output circuit that receives the oscillating signal which is supplied to the amplifier circuit, and outputs the received oscillating signal to outside. Here, the output circuit includes a first buffer that (i) receives at an input end thereof the oscillating signal which is supplied to the amplifier circuit and outputs the received oscillating signal, and (ii) uses a capacitance component of the input end to feed a first current signal back to the amplifier circuit, wherein the first current signal has a phase displaced from a phase of a voltage component of the oscillating signal, and a second buffer that (I) receives at an input end thereof the oscillating signal which is output from the first buffer and outputs the received oscillating signal, and (II) uses a capacitance component of the input end to feed a second current signal back to the first buffer, wherein the second current signal has a phase displaced from a phase of a voltage component of the oscillating signal which is output from the first buffer. |
