BANDGAP REFERENCE GENERATION FOR MULTIPLE POWER SUPPLY DOMAINS

Apparatus and methods for bandgap reference generators are disclosed. In certain embodiments, a bandgap reference generator includes a low voltage bandgap reference circuit that generates a first bandgap reference voltage, a high voltage bandgap reference circuit that generates a second bandgap reference voltage, a bandgap selector circuit that outputs the first bandgap reference voltage or the second bandgap reference voltage as a selected bandgap reference voltage based on a voltage level of the power supply voltage, and a bandgap translator circuit that generates a buffered bandgap reference voltage based on the selected bandgap reference voltage.
