Abstract
An oscillator equipped with a temperature compensation circuit is illustrated. Through the temperature compensation circuit, a transistor of a current mirror circuit of the oscillator which outputs a reference current to a voltage matching circuit is controlled by the temperature compensation voltage. Both of the temperature compensation voltage and a reference current decrease as the temperature rises, and a delay time of the oscillation voltage is proportional to the temperature compensation voltage and inversely proportional to the reference current. Therefore, the effects of temperature on the delay time just cancel each other out. The delay time of the oscillating voltage is related to the frequency of the clock signal. Therefore, if the delay time of the oscillating voltage is not affected by temperature, the frequency of the clock signal will not be affected by temperature.
