An oscillation circuit which generates an oscillation signal synchronous with given reference clock. The oscillation circuit is provided with a voltage controlled oscillation section, which stops oscillation of an oscillation signal having a frequency corresponding to a given control voltage by having each edge of the reference clock as a trigger and starts new oscillation; a phase comparison section which compares the phase of a comparison signal having a phase corresponding to the oscillation signal outputted from the voltage controlled oscillation section with a phase of a signal having a phase corresponding to the reference clock; and a voltage control section which supplies the voltage controlled oscillation section with a control voltage corresponding to the comparison results obtained from the phase comparison section. |
