Circuit arrangement for load regulation in the receive path of a transponder

A transponder comprising:

• an antenna for receiving a high frequency electromagnetic carrier signal for supplying energy to the transponder and for data communication with at least a transmitting station, the antenna being arranged between a first and second input of the transponder;
• and
• a receive path following the antenna in which a demodulator circuit is arranged for demodulating a received modulated signal that is derived from the high frequency electromagnetic carrier signal, wherein the demodulator circuit has a detector circuit comprising:
• an input for receiving a signal derived from the high frequency electromagnetic carrier signal;
• a circuit component for detecting and analyzing a signal voltage, the circuit component including, following said input, a signal capacitor across which a signal voltage dependent on the field strength of the high frequency electromagnetic carrier signal drops, and an analysis circuit following the signal capacitor for analyzing the signal voltage;
• and
• a circuit arrangement for load regulation that draws a discharge current from the circuit component in the event that a magnitude of the signal voltage exceeds a predetermined threshold.
