Circuit configuration for generating a reference potential

A circuit configuration for generating a reference potential, comprising:

• a first transistor having an emitter connected to a ground potential, a base, and a collector connected to said base;
• a second transistor having a base connected to said base of said first transistor a collector and an emitter;
• a first resistor connected between said collector of said first transistor and an output terminal outputting the reference potential;
• a second resistor connected between said collector of said second transistor and said output terminal;
• a third resistor connected between said emitter of said second transistor and ground potential;
• a third transistor having a base connected to said collector of said second transistor, and an emitter connected to the ground potential;
• a fourth transistor having a collector connected to a supply potential, an emitter connected to said output terminal, and a base connected to a collector of said third transistor;
• a fourth resistor coupled to said emitter of said fourth transistor and to said second resistor;
• a first current source connected between said base and said collector of said fourth transistor;
• a second current source connected in parallel with said first current source, said second current source generating a compensation current compensating for current fluctuations of said first current source;
• and
• a controller responsive to an output at said output terminal for providing control to said first and second current sources.
