A circuit for setting the operating point of a BGR circuit is disclosed. In the circuit, a voltage comparator (P 5 , P 6 , I 3 ) compares the output voltage of an operational amplifier of the BGR circuit with the voltage dropping across an auxiliary circuit branch (R 5 , D 3 ). The auxiliary circuit branch (R 5 , D 3 ) resembles the arrangement of a circuit branch (R 3 , D 1 ) of the BGR circuit, and a current source (P 8 ) generates as a function of the result of the comparison a setting current that is fed into an input of the operational amplifier.
