Abstract: A regulated voltage generator provides different regulated voltages to an integrated circuit. The regulated voltage generator includes a bandgap reference circuit and at least one gain stage connected to an output thereof. The output voltage of the bandgap reference circuit varies as a function of temperature to compensate for variations in the gain stage made up of first and second transistors. A regulated voltage output by the regulated voltage generator is independent of temperature and of the supply voltage. The value of the regulated voltage is adjusted via a load resistor and via the first and second transistors along with an output transistor of the bandgap reference circuit.
