1. A voltage generation circuit, comprising:

  • a voltage producing circuit that receives an input voltage and outputs an output voltage at an output terminal, and the voltage producing circuit having a control terminal;

    a comparison circuit operatively connected to the voltage producing circuit, the comparison circuit operating to compare a feedback signal received at an input terminal with a reference signal to produce a feedback signal that is supplied to the control terminal of the voltage producing circuit;

    a first feedback circuit operatively connected to the output terminal of the voltage producing circuit and to the comparison circuit, the first feedback circuit providing a first feedback signal to the input terminal of the comparison circuit; and

    a second feedback circuit operatively connected to the output terminal of the voltage producing circuit and to the comparison circuit, the second feedback circuit providing a second feedback signal to the input terminal of the comparison circuit.
