Abstract
The invention relates to a method for adjusting a BGR circuit. In a first adjustment step, an offset adjustment of a voltage differential amplifier is performed at a predetermined temperature. In a second adjustment step, the reference voltage generated by the BGR circuit is regulated to as predetermined value of the reference voltage at the predetermined temperature by setting a variable resistance of an external circuitry of the voltage differential amplifier.
