Abstract

The present invention relates to a reference voltage generator, which includes a first current source, an output current mirror, an output device and a current divider. The first current source generates a first current and has a first temperature coefficient. The output current mirror mirrors the first current and generates a second current in response to the first current. The output device provides a reference voltage in response to the second current. The current divider has a second temperature coefficient that is complementary to the first temperature coefficient, and is coupled in parallel to the output device in an operable manner.
