Abstract:
1. A voltage generating apparatus, comprising: a voltage generator, comprising an output node, for generating a first output voltage from the output end, wherein the first output voltage rises in response to a rising temperature and a current flowing from the output node of the voltage generator is fixed, and wherein the first output voltage decrease when the temperature is fixed and the current flowing from the output node of the voltage generator increases; and a current splitter, coupled to the output end of the voltage generator, for increasing the current flowing through the current splitter when the temperature rises, wherein the current splitter comprises a plurality of transistors coupled in serial each of the transistors comprises a gate, a first drain/source, a second drain/source, and a base; and the base is coupled to the first drain/source, and the gate is coupled to the second drain/source.
