One aspect of the invention relates to a rectifier circuit for providing a rectified voltage, with a first AC voltage terminal to which an AC voltage can be applied, with a first DC voltage terminal to which a DC voltage can be provided, and with a control switching element between the first AC voltage terminal and the first DC voltage terminal. The control switching element only couples the first AC voltage terminal to the first DC voltage terminal if the electrical potential at the first AC voltage terminal has a predeterminable polarity compared with a reference potential and if the amount of the electrical potential at the first DC voltage terminal is less than or equal to the amount of the electrical potential at the first AC voltage terminal.

The invention relates to a label identification system comprised of a transmitting-receiving unit and of identification labels on which the identification information is stored in the form of a digital identification information word. The provision of a circuit on the identification label in the form of a circuit arrangement, which is prefabricated using a polymer technique and on which the identification information is subsequently placed by the offset printing of conductor tracks, enables the provision of an identification label involving a minimal consumption of energy during inexpensive mass production. The bulk of the identification information processing is transferred to the transmitting-receiving unit.

The invention relates to an electronic component that can be operated by means of an alternating voltage. Said component includes at least one input, at least one output and a pair of electronic sub-components with an identical function. The input(s) of the electronic component is/are coupled to a respective input of the electronic sub-components with an identical function and the output(s) of the electronic component is/are coupled to a respective output of said electronic sub-components. In addition, the electronic component is configured in such a way that at least one output only one output signal of the first sub-component of the pair of functionally identical electronic components can be picked up during a first half-wave of an alternating voltage, whereas only one output signal of the second sub-component of the pair of functionally identical electronic can be picked up during the second half-wave of the alternating voltage.

摘要:
Sensor elements are arranged in a hexagonal grid. A processor element in the form of a primitive automaton is assigned to each of the sensor elements in the grid. The processor elements are set up to perform algorithms which enable lines of a fingerprint to be simplified such that characteristic minutiae of the fingerprint (endings and branchings of the lines) can be extracted. The processor elements are embodied using CMOS/Neuron MOS threshold value logic or using CMOS/NMOS pass transistor logic. The image grid can be read out via read-out circuits as a matrix.

A magnetoresistive memory is described and contains a common word line voltage source, bit lines, word lines crossing the bit lines, and a memory cell array having memory cells with cell resistors. The memory cell array further has reference cells with reference cell resistors. The memory cell array is configured such that for testing a respective cell resistor in each case two of the reference cell resistors nearest the respective cell resistor and the reference cell are simultaneously connected to a common word line voltage. A first feedback amplifier together with the two reference cell resistors form a summing amplifier. A second feedback amplifier together with the respective cell resistor form an amplifier having an equivalent gain as the summing amplifier. A comparator is connected to the summing amplifier and the amplifier. The comparator has an output supplying an evaluation signal dependent on the respective cell resistor.

In an arrangement for signal transmission between chip layers of a vertically integrated circuit, a defined, capacitive signal transmission ensues between a part of the vertically integrated circuit in one chip layer and a further part of the vertically integrated circuit in a further chip layer by means of a coupling capacitance. Particularly given high connection densities, a large number of freely placeable and reliable vertical signal connections can be produced directly from the inside of one chip layer to the inside of a neighboring chip layer without extremely high demands being made on the adjustment of the chip layers relative to one another and on the surface planarity of the individual chip layers.
