摘要 |
A transponder power supply for providing a supply current based on an antenna input signal. The transponder power supply comprises an emergency circuit comprising a charging circuit, an emergency capacitor, and an output stage. The charging circuit is configured to charge the emergency capacitor based on the antenna input signal to a maximum voltage which is higher than a voltage of the antenna input signal. The output stage is configured to provide a contribution to the supply current using a charge of the emergency capacitor. |
