Title:
OSCILLATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/008879
Kind Code:
A1
Abstract:
The purpose of the present invention is to obtain an oscillation signal of high spectral purity. An oscillation device 10 pertaining to an embodiment is equipped with: an oscillator 11 wherein the oscillation frequency cannot be controlled; a multiplier 85 for multiplying the frequency of an output signal of the oscillator 11 by a prescribed multiplication factor; a divider 83 for dividing an output signal of the multiplier 85 by a prescribed division ratio; a first signal combining part 82 for combining output signals of the divider 83 with an output signal of the multiplier 85; a frequency offset detection part 12 for detecting a frequency offset between the frequency of the output signal of the oscillator and the nominal frequency of the oscillator 11, on the basis of the output signal of the oscillator 11; a correction signal generation part 14 for generating a correction signal on the basis of the frequency offset, multiplication factor, and division ratio; and a second signal combining part 16 for combining the correction signal with an output signal of the first frequency combining part 82 in order to correct the frequency of the output signal of the first frequency combining part 82.
