  • Precision reference circuit
    Patent number: 11526191
    Abstract: An electronic device includes a precision reference circuit, which contains a bandgap reference circuit and an offset-correction circuit. The bandgap reference circuit has an output that is coupled to provide a bandgap reference voltage and an intermediate node that is separated from the output by a transimpedance resistor. The offset-correction circuit is coupled to the bandgap reference circuit and includes a DAC. The DAC is coupled to the intermediate node and is also coupled to receive an external digital value. The external digital value determines a fraction of a correction current that will be passed by the DAC.
