Abstract
A power voltage supply device, including a reference bias voltage generating circuit, a temperature compensation bias voltage generating circuit, a compensation voltage generator, and a voltage buffer, is provided. The reference bias voltage generating circuit generates a reference bias voltage. The temperature compensation bias voltage generating circuit generates a temperature compensation bias voltage that changes as temperature rises. The compensation voltage generator generates a first power voltage based on the reference bias voltage, and selectively boosts the first power voltage based on the temperature compensation bias voltage. An input terminal of the voltage buffer receives the first power voltage. The voltage buffer generates a second power voltage corresponding to the first power voltage to a load circuit.
