  • Circuit for generating reference voltage
    Patent number: 9035694
    Abstract: Provided is a circuit for generating a reference voltage. The circuit includes a band gap circuit generating a first current having a size that increases in proportion to an absolute temperature and a second current having a size that decreases in proportion to the absolute temperature, and outputting a reference voltage based on the first current and the second current; a mirroring circuit mirroring a sum of the first current and the second current and outputting a mirroring voltage that is in proportion to the sum of the first current and the second current; and a start-up circuit receiving the mirroring voltage from the mirroring circuit and providing a driving current for generating the first current or the second current to the band gap circuit until a time when the first current starts to be generated in the band gap circuit.
