Dual-mode data carrier and circuit for such a data carrier with
potential equalizing means for equalizing the potentials of at least
two contact terminals
摘要:
A data carrier (1) which can be operated in a contact-bound mode and in a contactless mode and a circuit (1A) for such a data carrier (1) has supply voltage generating means (35) for deriving a supply voltage (VDD), for various circuit sections of the data carrier (1) and of the circuit (1A), from a received useful HF signal (HF), and, in addition, potential equalizing circuit (94) by which at least two contact terminals (17A, 19A) each connected to a respective transmission contact (17, 19) can be brought at the same potential (ground).
