Abstract: A voltage generating apparatus including a voltage generator and a current splitter is provided. The voltage generator has an output node, and generates a first output voltage from the output node. The first output voltage rises when the temperature rises and the current flowing from the output end of the voltage generator is fixed. And the first output voltage drops when the temperature is fixed and the current flowing from the output node of the voltage generator rises. The current splitter is used for increasing the current flowing through the current splitter when the temperature rises. Therefore, the rise of the first output voltage of the voltage generator will be restrained, and the temperature compensation can be achieved.
