A circuit arrangement for simulating a sensor includes two external connections configured to change at least one of a current intensity and a resistance between the two external connections as a function of a measured variable. The circuit arrangement comprises: (a) a current path connecting the two external connections having two field-effect transistors and a resistor, and (b) a circuit configured to actuate gates of the two field-effect transistors so as to at least one of control and regulate a current through the current path, wherein the resistor is configured as a shunt resistor connected to a bridge rectifier and the circuit configured to actuate the gates of the two field-effect transistors comprises a control circuit configured to detect and regulate the current in the current path via a voltage drop at the shunt resistor. |
