    Abstract: An oscillation circuit includes an oscillation amplifier circuit that causes an oscillating element to oscillate to generate an oscillation signal, and a correction circuit connected with the oscillation amplifier circuit. At least a power supply voltage is input to the oscillation amplifier circuit. The oscillation amplifier circuit has a frequency variation characteristic that the frequency of the oscillation signal varies in response to variations in the power supply voltage. The power supply voltage is input to the correction circuit. The correction circuit corrects the frequency variation characteristic by using variations in the power supply voltage. The correction circuit may include a first variable capacitance element, and the first variable capacitance element may have a capacitance-voltage characteristic by which the frequency variation characteristic is reduced.

When the output circuit operates in the second state, the temperature compensation circuit outputs a second temperature compensation signal that compensates for a frequency-temperature characteristic when the output circuit operates in the second state, and the clock signal generation circuit generates a clock signal based on the second temperature compensation signal.
