<p><P>PROBLEM TO BE SOLVED: To provide an easy-to-manufacture data carrier while reducing sensitivity to changes in current consumption. <P>SOLUTION: The data carrier 1 includes a coupled device 2 that receives an amplification signal and takes energy from an electric field; a rectifying circuit 3 connected to the output side of the coupled device 2; a parallel control circuit 4 connected to the rectifying circuit 3; a first measuring device 5 providing a first signal 6 that depends on current consumption via the coupled device 2; and a demodulator 7 for demodulating the first signal 6. The data carrier 1 further includes a second measuring device 8 providing a second signal 9 that depends on the current consumption (i<SB>dyn</SB>) of a dynamic current consumption circuit 13, and a coupled device 10. The coupled device 10 forms a third signal 11 for supply to the demodulator 7 from the first and second signals 6, 9 so that dependence on the current consumption (i<SB>dyn</SB>) is at least partially compensated. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
