The present invention relates to a wire-bound transmission of data, as occurs, for example, between a sensor and a control unit. In order to save lines, both the supply voltage and the data signal to be transmitted are transmitted over the same line. The field of the present invention relates to the extraction of data signals from the supply voltage line.

A micromechanical sensor having an analyzer circuit and at least two detecting elements, each of the two detecting elements being connected to the analyzer circuit by at least one signal line. At least one signal line is connected to both detecting elements.

In a method for determining the reset time in a pressure sensor that detects the pressure in a combustion chamber of an internal combustion engine and emits a corresponding pressure signal, with the pressure curve in the combustion chamber having at least one high-pressure region the reset time is determined as a function of at least one pressure value detected in the high-pressure phase, so that it is possible, within the sensor, to determine a favorable time at which to reset the drift, based on the pressure range. In the method, information about the auxiliary rotation speed is determined based on the pressure curve of the compression phase and is then used to generate the reset time, the method entails only slight circuitry-related expense and can therefore be implemented even in an ASIC without complex signal processing, and the method functions in almost all known engine operating states.

A circuit for converting the capacitive signal change of a differential capacitor into digital signals, the circuit including a sigma delta modulator. The differential capacitor is a component of the signal feed structure and the reference feedback structure of the sigma delta modulator.

Sigma delta modulator

An electronic device includes a resonant circuit and an evaluation circuit. The resonant circuit includes an acceleration-sensitive sensor which is excited to vibrate during a testing phase of the acceleration-sensitive sensor. The evaluation circuit is coupled to the resonant circuit to determine a performance reliability of the acceleration-sensitive sensor.
