Data carrier with controllable supply voltage generation means
First Claim
1. 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.

Abstract
A data carrier (1) on which a carrier signal (TS) can be applied to an electric circuit (3), comprises supply voltage generation means (6) which are arranged for generating a DC supply voltage (U) that can be tapped from a supply tapping point (10) while use is made of the carrier signal (TS), and further includes control means (11) for controlling the DC supply voltage (U) in accordance with a controlled variable signal (CV) that represents the carrier signal (TS) occurring at a control means circuit point (20), and further includes decoupling means (49) with the aid of which the control means circuit point (20) and the supply circuit point (10) can be decoupled from each other.
