CIRCUIT ARRANGEMENT AND METHOD FOR OPERATING A CIRCUIT ARRANGEMENT |
摘要 |
A circuit arrangement for a transponder comprises a control circuit and an input circuit, wherein the input circuit comprises a first resonator, which comprises a first coil and a first capacitor, and a second resonator, which comprises a second coil and a second capacitor. The first capacitor and the second capacitor are designed as a first varactor and as a second varactor, respectively. Furthermore, the first resonator and the second resonator are designed in such a way that they can be used to provide a first output voltage and a second output voltage, respectively. Moreover, the control circuit is designed in such a way that it can be used to control at least one of the varactors so that a resonant frequency of the corresponding resonator can essentially be set to a predefined transmission frequency such that the output voltage of the corresponding resonator of the input circuit can be increased. |
