Abstract
An oscillator disclosed herein includes an oscillation circuit including a negative resistance element, a voltage bias circuit applying voltage to the oscillation circuit. The oscillator further includes a switch provided in a path, in which the voltage bias circuit and the oscillation circuit are electrically coupled to each other, and implementing switching between a conductive state and a non-conductive state of the path, and a constant voltage element electrically coupled in parallel to the switch.
