<P>PROBLEM TO BE SOLVED: To provide an oscillation device that reduces a memory capacity. <P>SOLUTION: The device includes: a frequency difference detection section for determining a difference-corresponding value corresponding to a difference value between a value corresponding to a difference between f1 and f1r and a value corresponding to a difference between f2 and f2r, where f1 is an oscillation frequency of a first oscillation circuit, f1r is an oscillation frequency of the first oscillation circuit at a reference temperature, f2 is an oscillation frequency of a second oscillation circuit, and f2r is an oscillation frequency of the second oscillation circuit at the reference temperature; and a correction value acquisition section for acquiring a frequency correction value for f1 owing to an ambient temperature different from the reference temperature on the basis of the difference-corresponding value x detected by the frequency difference detection section. The correction value acquisition function has the function of determining the frequency correction value for f1 by calculating an nth order polynomial with respect to X which is a value equivalent to x/k, where k is a division factor specific to the device. This configuration reduces the coefficients of the polynomial. <P>COPYRIGHT: (C)2013,JPO&INPIT |
