ABSTRACT:
A bandgap reference voltage circuit is provided, in which an additional resistor as well as a transistor is utilized to prevent the source-drain voltage of a metal oxide semiconductor field effect transistor electrically connected to an output terminal of the bandgap reference voltage circuit from falling into the triode region. Through the provided bandgap reference voltage circuit, the temperature compensation effect is able to be normally executed, so as to supply a stable bandgap reference voltage.
