Abstract
In some aspects of the present disclosure, a bandgap reference circuit includes a first current mirror and a first resistor coupled to the first current mirror to provide a proportional to absolute temperature (PTAT) voltage. The circuit includes a second current mirror and a bipolar junction transistor (BJT) device coupled to the second current mirror to provide a complementary to the absolute temperature (CTAT) voltage. The circuit includes an output node to provide a bandgap voltage that is a weighted sum of the PTAT voltage and the CTAT voltage. The circuit includes a second resistor coupled between the output node and a first node, wherein the first node is coupled between the first resistor and the first current mirror. The circuit includes a third resistor coupled between the output node and a second node, wherein the second node is coupled between the BJT device and the second current mirror.
