摘要： A storage circuit arrangement for a semi-passive or passive RFID transponder is provided. In prior-art circuit arrangements, storage capacitors are routinely discharged in an undefined fashion via leakage currents for a control mode of the transponder, so that the persistence times depend greatly on the ambient temperature and on existing manufacturing tolerances. It is proposed according to an embodiment to charge a first electrical storage device with a first reference voltage and then to discharge it again in a defined fashion during a time t via discharge device. Advantageously, in addition a storage mode of the first storage device to hold the control mode can be transmitted in a controlled fashion via a switching device to a second storage device with C2

The antenna includes two antenna branches that extend outward from a connecting region in which the antenna branches can be connected to the integrated receive circuit, and a yoke-shaped first trace segment that is designed to connect the two antenna branches together. Each antenna branch can have a U-shaped second trace segment connected to the connecting region, and a U-shaped third trace segment connected to the second trace segment and extending parallel to the second trace segment. The invention further relates to a backscatter-based RFID transponder with such an antenna.

摘要： A circuit arrangement for phase modulation in an input circuit of a backscattering transponder includes a varactor and at most one capacitor connected in series between two antenna terminals, as well as a varactor control arrangement applying a control voltage to the varactor to selectively vary the capacitance thereof. One of the antenna terminals is connected directly to one of the varactor terminals without a capacitor therebetween. The other antenna terminal is connected either directly or through a capacitor to the other varactor terminal. One antenna terminal and/or one varactor terminal can be grounded. A DC-decoupling capacitor can be connected between a transponder circuit unit or a circuit ground and the common junction of the antenna terminal with the varactor terminal. The circuit arrangement is simple, economical, and uses minimal chip area by omitting further capacitors between the antenna terminals.

摘要： For transmitting data, a receiving/backscattering arrangement receives, modulates and reflects or backscatters electromagnetic waves emitted by a base station. The modulation corresponds to the data to be transmitted and is carried out selectively using first and/or second different modulation methods depending on the received field strength of the received electromagnetic waves. Preferably, phase shift keying is used especially or at least at low field strengths at far range, while amplitude shift keying is used additionally or alternatively for high field strengths at close range. The two modulation methods can be superimposed. A circuit arrangement includes two different modulator arrangements to perform the two modulation methods depending on the received field strength. The second modulator arrangement preferably comprises a multi-stage voltage multiplier circuit with a modulated switching device intervening in one of the stages to achieve the modulation.

摘要： A circuit arrangement for detecting a received signal includes a rectifier with an input connected to a receiving antenna for rectifying an encoded received signal, a signal capacitor connected to an output of the rectifier, a discharge current sink connected to the signal capacitor, and a signal evaluating circuit connected to the signal capacitor. The discharge current sink includes a current mirror circuit of cascode-connected transistors. Thereby, the discharge current is substantially independent of the signal voltage over a larger range of voltages. This signal detection circuit is useful in transponders or remote sensors that receive and detect a signal transmitted by a base station.

摘要： A fluid applicator includes a coating implement, an elastic closure cap, and a stopper for use with a fluid container. The elastic closure cap includes an enlarged irregular sealing rib on a skirt that is force-fit into the stopper, creating a resilient force on a sealing lip that contacts a seat on the stopper. Inverting the container and pressing on the coating implement, presses the elastic closure cap, deforming it to move the sealing lip off of its seat on the stopper to allow fluid flow from the container, through the stopper and elastic closure cap, to the coating implement.
