ABSTRACT:
A reference voltage generator includes a first current source, an output current mirror, an output device, and a shunt device. 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 shunt device has a second temperature coefficient that is complementary to the first temperature coefficient, and is operatively coupled in parallel with the output device.
