Abstract

Circuit arrangement, including a first resistor, a second resistor, a current source and an analog-to-digital converter. The second resistor is thermally coupled to the first resistor. The current source is coupled to the second resistor. The analog-to-digital converter is configured to receive a first voltage measured via the first resistor as a voltage to be digitized, and is configured to receive a second voltage measured via the second resistor as a reference voltage of the analog-to-digital converter.
