Abstract
A bandgap voltage generator circuit is formed using only bipolar transistors. The bandgap voltage generator circuit includes an output node at which a bandgap reference voltage is generated. A transconductance amplifier circuit in a current control feedback loop has a differential input which receives a base current. A compensation current sink circuit operates to sink a compensation current from the output node corresponding to the base current received at the differential input of the transconductance amplifier.
