Abstract
A data carrier, in particular a smart card, is described and has at least one transmitting/receiving antenna and also a rectifier circuit connected downstream thereof and serving for providing a supply voltage for at least one circuit unit. A voltage regulating circuit is connected in parallel with the supply voltage terminals of the circuit unit. The voltage regulating circuit has an output at which a signal proportional to a regulating signal of the voltage regulating circuit can be tapped off. This output is connected to the control input of a controllable clock signal generator, which provides the clock signal for the at least one circuit unit.
