| Zusammenfassung: | A current reference circuit configured to generate a reference current with a programmable temperature slope is disclosed. The current reference circuit includes a resistor. The current reference circuit includes a bandgap voltage circuit configured to generate a bandgap voltage and coupled to the resistor. The current reference circuit includes a bias voltage circuit configured to generate a variable-polarity bias voltage and coupled to the bandgap voltage circuit. The bandgap voltage circuit is configured to add the variable-polarity bias voltage to the bandgap voltage to generate the reference current through the resistor. |
