Beschreibung
Zusammenfassung:	A circuit includes first, second, and third power supply terminals. The circuit includes an input node coupled to receive a negative voltage and an output node coupled to provide a positive voltage proportional to the negative voltage. The circuit includes a voltage-to-current converter coupled to the first power supply terminal and the input node and configured to generate an intermediate current proportional to the negative voltage at the input node. The circuit also includes a current mirror coupled to the second power supply terminal and third power supply terminal and configured to mirror the intermediate current through a first resistor to provide the positive proportional voltage.
