ABSTRACT:
A circuit for generating a reference voltage which is independent of temperature and supply voltage includes a bandgap stage supplying the reference voltage, a first circuit receiving the supply voltage and generating an output voltage being substantially free of variations in the supply voltage, and a second circuit connected to the first circuit and driven by the output voltage, the second circuit being connected to the bandgap stage for supplying a current to the bandgap stage having a characteristic for compensating and eliminating temperature dependencies in the bandgap stage.
