摘要：An oscillation device capable of highly accurate temperature compensation ofan output frequency is provided. The oscillation device includes: first and secondoscillator circuits oscillating first and second quartz-crystal resonators with overtonesrespectively; a frequency difference detecting part finding a value corresponding to adifference value between values corresponding to differences between f1 and f1r andbetween f2 and f2r, where f1 and f2 are oscillation frequencies of the first and secondoscillator circuits, and f1r and f2r are oscillation frequencies of the first and secondoscillator circuits at a reference temperature; and a correction value obtaining part which,based on the value corresponding to the difference value and a relation between thevalue corresponding to the difference value and a frequency correction value of theoscillation frequency f1, obtains the frequency correction value of f1, wherein the outputfrequency is corrected based on the found frequency correction value.
