Abstract
An active type temperature compensation resonator structure is provided, including a resonant body and a temperature compensation element embedded in the resonant body for a compensation current to pass therethrough. The temperature compensation element has a specified temperature coefficient of resistance that reflects the temperature of the resonant body. The magnitude of the compensated current corresponds to the reflected temperature of the resonant body. With the active type temperature compensation resonator structure, the temperature of the resonant body can be accurately reacted by the specified temperature coefficient of resistance, such that the temperature compensation element, through which the compensated current passes, can dynamically correspond to the temperature of the resonant body and accurately provide the resonant body with temperature compensation.
