Bandgap reference circuit

摘要

A bandgap circuit includes a current mirror that generates a proportional to absolute temperature current at an output node that outputs the bandgap reference voltage. A first current path including a first resistor is coupled between the output node and a first bipolar transistor. The second current path including a second resistor is coupled between the output node and a second bipolar transistor. The first current path is parallel to the second current path. The circuit outputs a bandgap reference voltage.
