Abstract
An oscillation circuit includes an oscillating circuit adapted to oscillate a resonator element having a frequency-temperature characteristic, and a frequency adjustment circuit having a capacitance circuit connected to the oscillating circuit and adapted to adjust an oscillation frequency of the oscillating circuit, and a logic circuit, to which a signal having been output from the oscillating circuit is input, and which adjusts a frequency of the signal, and the frequency adjustment circuit compensates the frequency-temperature characteristic using at least the capacitance circuit in a predetermined temperature range, and compensates the frequency-temperature characteristic using the logic circuit alone outside the predetermined temperature range.
