摘要： A method and circuit for wireless data transmission between a base station and one or more transponders is provided in which the base station modulates a carrier signal with a modulation signal and transmits it, in which symbols that are to be transmitted are coded by the base station using sequential delimiters. A value of a particular symbol being determined by the time period between two sequential delimiters, and in which the particular delimiter is generated by changing the modulation signal during a modulation period. Whereby, the modulation signal is preferably a noise signal during the modulation period.

摘要： A receiving/backscattering arrangement for carrying out a contactless data transmission includes an integrated circuit having two antenna contacts, a series arrangement of three high quality capacitances connected between the two antenna contacts, whereby the middle capacitance is an MOS varactor, a controllable variable voltage source connected across the MOS varactor, and a control unit that controls the voltage source. The receiving/backscattering arrangement is especially a passive transponder with a rectifier connected between the antenna contacts, or a semi-passive transponder including a battery or solar cell, to provide the required supply voltage for the circuit. The arrangement achieves a large communication range, for receiving and modulating an interrogation signal, and backscattering the modulated response signal with a high efficiency and low losses. The integrated circuit structure is compact and economical.

摘要： In a method of transferring data from a transponder to a reading device in a scanning identification system through load-modulation of an inquiry signal emitted by the reading device, with the transponder being initialized at the beginning of the reception of the inquiry signal and responding with the emission of the response signal, first a predetermined number of data bits that are not part of the response signal are transmitted, and a terminator sequence followed by the response signal are repeatedly transmitted, until the inquiry signal is interrupted. The time required by the reading device for building up the inquiry field is bridged by the predetermined number of data bits and, at the same time, the reading device is synchronized to the clock of the response signal. Through the terminator sequence, which indicates the beginning of a valid response signal, the response signal is already recognized correctly by the reading device during the first transfer.

摘要： A method and device for selecting one or more transponders, in particular backscatter-based transponders, from a plurality of transponders by a base station, which method is based on a slotted ALOHA method, in which the base station defines numbered time slots and a random number generated in a given transponder determines a time slot when the transponder transmits its transponder-specific identification to the base station. The random number is generated in a given transponder with the aid of a random number generator, the relevant random number generator is switched into a counter operating mode after reception of a selection command transmitted by the base station, while a count state of the random number generator is decremented or incremented when the base station transmits the start of a time slot, the relevant transponder transmits a transponder-specific identification to the base station if the count state of its random number generator is equal to a predetermined value, and the relevant random number generator is then switched back into the operating mode for random number generation.
