Abstract
A circuit apparatus includes a clock signal generation circuit configured to generate a clock signal by a resonator, an output circuit configured to operate in a first state or a second state in which a consumption current is different from that in the first state and output an output clock signal, and a temperature compensation circuit configured to compensate for a frequency-temperature characteristic of the clock signal based on a temperature detection signal. When the output circuit operates in the first state, the temperature compensation circuit outputs a first temperature compensation signal that compensates for a frequency-temperature characteristic when the output circuit operates in the first state, and the clock signal generation circuit generates a clock signal based on the first temperature compensation signal. 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.
