Abstract

In accordance with various embodiments, a circuit arrangement may include a first circuit, which is designed for contactless communication, and a second circuit, which is designed in accordance with a predefined functionality. The circuit arrangement may further include at least one electronic component which in a first operating mode together with the first circuit implements the contactless communication and in a second operating mode together with the second circuit implements the predefined functionality.

Claims

1. A circuit arrangement, comprising:

a first circuit, which is designed for contactless communication;

a second circuit, which is designed in accordance with a predefined functionality;

at least one electronic component which in a first operating mode together with the first circuit implements the contactless communication and in a second operating mode together with the second circuit implements the predefined functionality.

2. The circuit arrangement of claim 1,

wherein the at least one electronic component is coupled to the first circuit and the second circuit.

3. The circuit arrangement of claim 1,

wherein the circuit arrangement is designed in such a way that the first operating mode and the second operating mode are implementable simultaneously.

4. The circuit arrangement of claim 1,

wherein the circuit arrangement is designed in such a way that it is possible to switch between the first operating mode and the second operating mode.

5. The circuit arrangement of claim 1,

wherein the first circuit is designed for near field communication.

6. The circuit arrangement of claim 1,

wherein the second circuit is designed for operation in a frequency range that is different than the frequency for operation in the second operating mode.

7. The circuit arrangement of claim 1,

wherein the second circuit is a DC voltage circuit.

8. The circuit arrangement of claim 1,

wherein the first circuit and the second circuit are electrically conductively connected to one another.

9. The circuit arrangement of claim 1,

wherein the first circuit and the second circuit are galvanically isolated from one another.

10. The circuit arrangement of claim 1,

wherein the electronic component comprises a coil or is formed by a coil.

11. The circuit arrangement of claim 1,

wherein the electronic component comprises a capacitor or is formed by a capacitor.

12. The circuit arrangement of claim 1,

wherein the electronic component comprises an ohmic resistor or is formed by an ohmic resistor.
