Abstract: The circuit has a defined voltage (VRef) applied to a memory cell (SZelle) read output via which a state of charge current (I1) flows. A regulating transistor (RT1) source-drain path is connected to the read output. A differential amplifier (DV1) output is connected to the regulating transistor gate and the regulating transistor gate voltage can be controlled by the differential amplifier so that the defined voltage is applied at the read output. Independent claims are also included for the following: a read-out circuit for determining state of charge of non-volatile semiconducting memory cells, a matrix arrangement of non-volatile semiconducting memory cells and an EEPROM, EAROM or Flash-EPROM memory component with a number of non-volatile semiconducting memory cells.

Abstract: A sensor arrangement including a control circuit is disclosed. In at least one embodiment, at least one sensor electrode can be charged and/or discharged therewith and a comparator unit for the comparison of a provided voltage for the at least one electrode with a reference voltage. A duration necessary for the charging/discharging of the at least one sensor electrode is determined, whereby, from the determined duration, it is determined whether a sensor event, in the form of a hybridization between trap molecules and the particles for recording, has occurred.

Abstract: An electrochemical sensor (100), as a biochip, has a sensor electrode (101) with immobilized catch molecules (105) on its surface, is new. One circuit (102) is coupled electrically to the sensor electrode as a potentiostat, and a second circuit (103) has a condenser (104). An electrochemical sensor (100), as a biochip, has a sensor electrode (101) with immobilized catch molecules (105) on its surface, is new. One circuit (102) is coupled electrically to the sensor electrode as a potentiostat, and a second circuit (103) has a condenser (104). The nominal potential of the sensor electrode is held in a reference range, with a link to the condenser for potential comparison. If the potential at the condenser is outside a second reference range it is corrected to the first reference potential. Each molecule to be caught (106) has an enzyme label (107). The specification is an addition to .

Abstract: Circuit arrangement having a sensor electrode, a first circuit unit, which is electrically coupled to the sensor electrode, and a second circuit unit, which has a first capacitor. The first circuit unit holds an electrical potential of the sensor electrode in a predetermined first reference range around a predetermined electrical desired potential by coupling the first capacitor and the sensor electrode such that there is a matching of their electrical potentials. If the second circuit unit detects the electrical potential of the first capacitor being outside a second reference range, the second circuit unit brings the first capacitor to a first electrical reference potential.

Abstract: The invention relates to a biosensor for detecting nucleic acids, comprising at least two units for immobilizing nucleic acids and one electrical detection circuit. Said units are electroconductive and electrically insulated from one another. The units are provided with first nucleic acid molecules that are present as single-stranded molecules and that are capable of binding second nucleic acids to be detected. These scavenger molecules are provided with a redox-active marker that is capable of producing a detectable signal. The electrical detection circuit is adapted to detect by means of the marker any nucleic acid molecules bound to the scavenger molecules.

Date Apr. 4, 1996A coupling arrangement for optically coupling together, in a self-aligning fashion, inputs and outputs of an optoelectronic integrated circuit module and end faces of optical fibers with the module being arranged with a plane support surface flat on a plane bearing surface of a holder for holding fibers and a stopping device is provided for limiting a relative displacement between the module and the holder at a point at which the mutually-assigned end faces and inputs and outputs of the module are situated opposite one another. The electrical contacting of the module is performed by a continuous opening in the holder so that contacts extend through the opening to engage a surface of the module.
