Abstract
The voltage generator provided by the present invention includes: a first current source, a second current source, a first resistor, a reference voltage generator, a first amplifier and a second amplifier. The first current source generates a first current and a second current with a first temperature coefficient according to a first bias voltage. The second current source generates a third current and a fourth current with a second temperature coefficient according to a second bias voltage. The reference voltage generator provides a first reference voltage and a second reference voltage according to the first and third currents. The first amplifier generates the first bias voltage according to the first and second reference voltages. The second amplifier generates the second bias voltage according to the second and third reference voltages. Wherein, the first temperature coefficient and the second temperature coefficient are complementary.
