Abstract
An oscillating device includes a heater, a thermoelectric cooler, a frequency source, a temperature controlled circuit, and a voltage controlled oscillation circuit. When the ambient temperature is in a low-temperature range, the temperature controlled circuit drives the heater to a target temperature to adjust an operating temperature of the frequency source. When the ambient temperature is in a high-temperature range, the temperature controlled circuit drives the thermoelectric cooler to the target temperature to adjust the operating temperature of the frequency source, and the voltage controlled oscillation circuit drives the frequency source to reduce a frequency variation of the frequency source resulted from the variation of the ambient temperature. Alternatively, the heater or the voltage controlled oscillation circuit may be omitted.
