Generating a supply voltage for a resistive sensor element

Abstract

A circuit arrangement for operating a resistive sensor element is described. According to an example implementation, the circuit arrangement includes a first supply terminal and a second supply terminal, between which is applied a supply voltage during operation, and a sensor circuit having at least one resistive sensor element. The sensor circuit has a first circuit node and a second circuit node for applying a sensor voltage, wherein the first circuit node is connected to the first supply terminal. The circuit arrangement further includes a sensor supply circuit, which is configured to electrically couple, during a measurement time interval, a charged capacitor to the second circuit node in such a way that the sensor voltage between the first circuit node and the second circuit node is greater than the supply voltage.
