DATA CARRIER COMPRISING AN INTEGRATED CIRCUIT WITH AN INTEGRATED MAIN CAPACITOR AND INTEGRATED ADDITIONAL CAPACITORS

摘要

A data carrier (1) comprises an integrated circuit (3), which integrated circuit (3) comprises a tolerance-defined main capacitor (35) which is connected to a coil (4) of the data carrier (1), and which integrated circuit (3) comprises at least one integrated additional capacitor (32) which is optionally connectable to the coil (4) of the data carrier (1) so that a parallel switching configuration of the main capacitor (35) with the at least one additional capacitor (32) is achievable. The optional parallel arrangement of the at least one additional capacitor (32) leads to a reduction of the tolerance range of the nominal capacitance of the main capacitor (35) when the effectively realized capacitance of the main capacitor (35) is reduced by a factor F and the at least one additional capacitor (32) has a fraction K of the nominal capacitance of the main capacitor (35).
