Abstract
An integrated circuit has an untrimmed bandgap generation circuit; and a bandgap generation circuit coupled to the untrimmed bandgap generation circuit. The bandgap generation circuit has a current source controlled by the 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 the 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.
