Abstract: The invention relates to a DNA chip comprising a carrier (14) and a microarray of spots (1) containing immobilised catcher molecules which are arranged on said carrier. Each spot (1) contains a microelectrode system for the impedance spectroscopic detection of binding events occurring between the catcher molecules and target molecules of an analyte solution (38) applied to the spots (1). The microelectrode system has a pair of polarisation electrodes (2,4) in order to produce an alternating electromagnetic field and a pair of sensor electrodes (8,10) for measuring a voltage drop in the analyte (38).

Abstract: The arrangement has a semiconductor device (1) including a semiconductor substrate (101), a doped region (103) adjacent to an upper side (102) of the substrate, and an insulating layer (104) adjacent to the region. A connection (201) of a power supply unit (2) is connected with an insulated gate structure (105), and another connection (202) is connected with a reference potential (GND). An input (301) of a measuring unit (3) is connected with the substrate, another input (302) is connected with the region, and an output (303) provides a measurement value that is proportional to a defect (106). An independent claim is also included for a method for operating a semiconductor device.

Abstract: A magnetoresistive memory includes a control circuit with a first pole that, via a reading distributor, can be individually connected to first ends of bit lines by switching elements. The control circuit also has a second pole, which supplies power to an evaluator, and has a third pole that is connected to a reference voltage source. The readout circuit additionally includes a third voltage source having a voltage, which is approximately equal to the voltage of the first reading voltage source and which can be individually connected to second ends of the bit lines by means of switching elements. Finally, the readout circuit includes a fourth voltage source, which can be individually connected to second ends of the word lines by means of switching elements.

Abstract: In a first phase a first sensor signal, essentially comprising the current offset signal of the sensor, is applied to the input of an electronic circuit. The first sensor signal is fed to a first signal path and stored therein. In a second phase a second sensor signal, comprising the current offset signal and a time-dependent measured signal, is applied to the input and the stored first sensor signal is fed to the input by means of the first signal path, such that essentially the time dependent measured signal is fed by means of a second signal path coupled to the input.

Abstract: A sensor array is provided including transistors that are coupled together. The transistors are designed as sensors and wherein the sensor array has switching devices for selecting a transistor and wherein the selected transistor's condition may be detected. The sensor array is set up so that the selected transistor is driven as a source follower and at least some of the transistors are MOS field effect transistors that are configured so that at least some of the transistors are capable of detecting biological material.

Abstract: The transistor arrangement contains a first and a second field effect transistor comprising a first and a second source drain connection and a control connection for applying a first or a second signal. The two field effect transistors are of the same conductive type. The transistor arrangement is configured in such a manner that the first signal can be applied in an alternating manner to the control connection of the first field effect transistor and the second signal can be applied in a simultaneous manner to the control connection of the second field effect transistor, and/or the second signal can be applied to the control connection of the first field effect transistor and the first signal can be applied simultaneously to the control connection of the second field effect transistor.
