Abstract
An oscillator includes a resonator, a temperature control element that controls a temperature of the resonator, a first temperature sensing element that outputs a first temperature detection signal, a second temperature sensing element that is provided at a position farther from the resonator than the first temperature sensing element and outputs a second temperature detection signal, an analog/digital conversion circuit that converts the first temperature detection signal into a first temperature code which is a digital signal, and converts the second temperature detection signal into a second temperature code which is a digital signal, and a digital signal processing circuit that generates a temperature control code for controlling the temperature control element based on the first temperature code and the second temperature code.
