Abstract
A voltage generating apparatus including a current source, a first voltage source, a second voltage source, a first differential pair, a second differential pair, a voltage divider and a current mirror is provided. The voltage divider is used for reducing a voltage with a negative temperature coefficient, so as to reduce the amplification ratio of the voltage with a positive temperature coefficient used for compensating the negative temperature coefficient.
