1. An integrated circuit, comprising:

  • an untrimmed bandgap generation circuit; and

    a bandgap generation circuit coupled to the untrimmed bandgap generation circuit, the bandgap generation circuit comprising;

    a current source controlled by said untrimmed bandgap generation circuit and coupled in series with a resistor and a first bipolar diode device,one or more of bipolar diode devices, each bipolar diode device coupled in parallel with said first bipolar diode device, wherein a trimmed bandgap reference voltage output of the integrated circuit is a function of the number of bipolar diode devices.
