In the present invention, a temperature compensation circuit is provided. The temperature compensation circuit includes a first oscillator for providing a first clock signal, a timer electrically connected to the first oscillator for clocking a specific time period, a voltage regulator for generating a constant voltage, a second oscillator electrically connected to the voltage regulator for providing a second clock signal, and a counter electrically connected to the second oscillator for counting within the specific time period based on the second clock signal so as to obtain a counting value, and thereby a frequency of the second oscillator is obtained for the temperature compensation.
