Title:
OSCILLATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/171607
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an oscillation device which achieves both expansion of frequency variable width and refinement of the variable pitch thereof. An oscillation device 1 is provided with: an oscillation unit 10; a frequency divider 20 that divides the frequency (f1) of an output signal of the oscillation unit 10 by a frequency division number N into a frequency (f1/N); a shift signal generation unit 30 that generates an analog shift signal oscillating at a predetermined frequency (f3); a first signal combination unit 40 that combines the shift signal with an output signal of the frequency divider 20 so as to convert the frequency (f1/N) of the output signal of the frequency divider 20 to a frequency (f1/N + f3) shifted by the shift frequency (f3); and a second signal combination unit 50 that combines an output signal of the first signal combination unit 40 with the output signal of the oscillation unit 10 so as to convert the frequency (f1) of the output signal of the oscillation unit 10 to a frequency (f1 + f1/N + f3).
