Apparatus for generating constant reference voltage signal regardless of temperature change

Abstract

The present invention provides a reference voltage signal generator capable of generating a constant reference voltage signal regardless of temperature variation by compensating a voltage signal change due to temperature variation. The reference voltage signal generator includes: a voltage signal generating unit receiving a power supply voltage signal and generating a first voltage signal; a regulation sense amplifier generating a regulation voltage signal by regulating the first voltage signal according to the variation of the power supply voltage signal; and a voltage distributing unit including a variable resistor for compensating a voltage signal variation according to a change in temperature, wherein the voltage distributing unit distributes the regulation voltage signal and outputs a feedback voltage signal dependent on temperature to the regulation sense amplifier, and a reference voltage signal independent of the temperature.
