    摘要: The chip-card can be coupled to an associated write-read unit either via a contact bank or via an antenna coil. The write-read unit supplies the card with its operating power via the coupling, which is also used for data exchange. Where coupling is effected via the antenna coil, a rectifier (5) is provided to supply power. To achieve maximum range, the rectifier (5) is directly connected to components requiring operating voltage. An A.C. recognition circuit (12) is provided to facilitate switching between these two operating modes. Alternatively, the contact which delivers the operating voltage in the case of contact coupling is de-coupled from the rectifier and a voltage recognition circuit is connected to that contact. When coupling is effected via the antenna coil, the circuit elements not required for this operating mode should be switched to a power-saving rest state. The memory access authorisations can be configured in different ways according to the particular operating mode. Also disclosed are various geometrical configurations of contact bank, chip and antenna coil on the chip-card.

    摘要: Proposed are two parallel control stages each with one transistor (T1, T2). The transistor (T2) forms part of the indirect parallel control stage and acts directly on the rectifier. It can take relatively high currents and is therefore relatively slow. The transistor (T1) forms part of the direct control stage and acts in parallel with the support capacitor. As a result of the coarse adjustment effected by transistor (T2), it is required to take only small currents and can therefore have very rapid control characteristics. Owing to the coarse adjustment effected by transistor (T2), the alternating voltage at the antenna connections (LA and LB) collapses rapidly if the HF signal is interrupted. This means that the transmission rate with pause interval modulation can be increased. Electrostatic chargings also derived from the transistor (T2), thus obviating the need for additional protective circuits.
