    摘要: A chip card includes a semiconductor chip that contains at least one memory. In order to supply energy to the chip and to provide for bi-directional data transmission from and to the chip, both contacts and a device for contactless data transmission are provided. A triggerable switch device which is provided on the chip connects the memory either to the contacts or to the device for contactless data transmission as a function of a state of an output signal of a logic circuit connected to at least a voltage supply contact. The switch device assumes a position of repose when it is not triggered and in that position it connects the memory to the device for contactless data transmission, while only upon application of a voltage to the supply voltage contact, triggered by the logic circuit, does it connect the contacts to the memory.

    摘要: A method for demodulating a voltage which has been ASK modulated by changing the amplitude between a low level and a high level, in particular for use during contactless data transmission from a card reader/writer to a smart card, is described. The method is distinguished, in that, in an initialization phase, a first mean value is produced from the high voltage level and a stored partial voltage derived therefrom in order to detect a change to a low voltage level. The change to the low voltage level represents a start value and is detected by a subsequent comparison of the modulated voltage with the first mean value. In a subsequent demodulation phase, a second mean value is produced from the detected low voltage level and the high voltage level in order to demodulate the modulated voltage by comparing the modulated voltage with the second mean value.

    摘要: A data transmission circuit having a station and a response circuit. The station has an amplitude demodulator as well as a primary coil with a signal generator for producing an alternating magnetic field at a carrier frequency. The response circuit has a secondary coil as well as an amplitude modulator for influencing a load on the secondary coil, and the amplitude modulator is configured such that the alternating magnetic field can be modulated with a data signal. Particularly when the data transmission circuit is mass-produced, situations frequently occur in which the data signal modulated onto the alternating magnetic field by the response circuit can no longer be reconstructed at the station end. The object of the invention is thus to provide a data transmission circuit of this generic type, which always operates reliably. According to the invention, the response circuit has a phase modulator for influencing the electrical characteristics of the secondary coil. The amplitude modulator and/or the phase modulator being configured such that it or they can be driven, in particular, by at least one activation signal.

A logic circuit processes the received, demodulated and decoded data. A first demodulator for demodulating received 100%-ASK-modulated signals and a second demodulator for demodulating received ASK-modulated signals with a modulation depth of less than 100% are provided. The second demodulator is triggered by the first demodulator in such a way that on reception of a 100%-ASK-modulated signal, it is deactivated by the first demodulator.
