Abstract: A bandgap reference voltage generator includes a bipolar assembly having a first resistor, a first branch and a second branch that is in parallel with the first branch. The first branch includes a first bipolar transistor with a base coupled to a fixed voltage. The second branch includes a second bipolar transistor with a base coupled to the fixed voltage and a second resistor coupled in series with the second bipolar transistor. A differential module is coupled to the first and second bipolar transistors and configured to balance the currents in the first and the second branches. The bandgap reference voltage is output at a node to which the first resistor is connected.
