Abstract:
A data carrier (1) comprising an electric circuit (3)which circuit has a circuit terminal (4) for supplying a carrier signal (TS), and includes supply voltage generation means (6) for generating a DC supply voltage (U) while the carrier signal (TS) is used, and which has a supply circuit point (10) from which the DC supply voltage (U) can be tapped, and which includes control means (11) for controlling the DC supply voltage (U) in accordance with a controlled variable signal (CV) that occurs at a control means circuit point (20) and represents the carrier signal (TS), characterized in that decoupling means (49) are provided with the aid of which the supply circuit point (10) and the control means circuit point (20) can be decoupled from each other.
