Bandgap voltage reference generator

A bandgap voltage reference generator formed in an integrated circuit for providing a predetermined output bandgap voltage comprising:

• a bandgap voltage supply circuit having and input suitable for connection to a voltage power source, a first output generating a voltage output in response to the voltage received by said bandgap voltage supply circuit input from the voltage power source, and a second output generating said predetermined output bandgap voltage in response to the voltage received by said bandgap voltage supply circuit input from the voltage power source, said bandgap voltage supply circuit comprising:
• a first current mirror having two outputs and an input, said input of said first current mirror being suitable for connection to the voltage power source, said first output of said first current mirror being coupled to said first output of said bandgap voltage supply circuit;
• a first biopolar transistor responsive to said first output of said first current mirror and coupled to said second output of said first current mirror and coupled to said second output of said bandgap voltage supply circuit;
• a first resistor responsive to a second output of said first current mirror;
• and
• a second biopolar transistor coupled to said first resistor and said first biopolar transistor;
• an amplifier circuit receiving the voltage from said first output of said bandgap voltage supply circuit and providing an amplified output signal in response thereto;
• and
• a voltage regulator controlled by the output signal of said amplifier and connected to the input of said bandgap voltage supply circuit so that said voltage regulator controls the voltage supplied to said input of said bandgap voltage supply circuit by the voltage power source so as to maintain the output voltage of said bandgap voltage supply circuit at the predetermined output bandgap voltage.
