Provided is a bandgap reference voltage generator without a start-up failure, including: a reference voltage generator, generating a bandgap reference voltage; a current provider providing a start-up current to the reference voltage generator using a predetermined power; and if the current provider fails to provide the start-up current to the reference voltage generator, a current providing support providing the start-up current to the reference voltage generator using the predetermined power used by the current provider. Therefore, when the bandgap reference voltage generator starts up by itself at an initial driving, a start-up failure does not occur. Thus, other electric elements integrated into an integrated circuit element can be supplied with a rated bandgap reference voltage and thus normally operate.
