Title:
デュアルモードデータ担体及び少なくとも二つの接触端子の電位を等化にする電位等化手段を備えるこのようなデータ担体用の回路
Document Type and Number:
Japanese Patent JP4216347
Kind Code:
B2
Abstract:
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).
