Abstract
An integrated circuit includes a voltage generator with a first controllable resistor and a second controllable resistor, through which a first input terminal that applies a first voltage potential and a second input terminal that applies a second voltage potential can be connected to an output terminal that generates an output voltage. In a manner dependent on the output voltage, a first comparator circuit generates a first control signal to control the first controllable resistor, and a second comparator circuit generates a second control signal to control the second controllable resistor. A control unit evaluates the control signals generated by the comparator circuits and drives the first and second controllable resistors of the voltage generator in such a way that in each case only one of the two controllable resistors has a low-resistance state.
