Abstract
An oscillator is comprising a plurality of resonators and a voltage bias circuit that applies voltages to the plurality of resonators. Each of the plurality of resonators has a negative resistance element. In the oscillator, the plurality of resonators are connected in parallel to the voltage bias circuit respectively via separate inductors.
