Abstract:
    Bandgap reference circuits. In the bandgap reference circuit, a current generation circuit generates an output current obtained by combining a first current, a second current and a third current. The first current is converted from a first voltage and a first forward voltage of a first constant voltage generation element. The second current and the third current are both converted from a voltage difference between the first forward voltage and a second forward voltage of the second constant voltage generation element. A current-to-voltage generator converts the output current to an output voltage.
