A component is provided for an impedance change in a coplanar waveguide which includes two grounding conductors and a signal line lying between the grounding conductors, as well as a conducting connecting element, which has a covering surface for the two grounding conductors and the signal line, and is electrically insulated, so that in each case a capacitor is formed. The connecting element and the lines are situated and arranged so that the respective capacitor between the grounding conductors and the connecting element has an invariable capacitance, but the capacitor between the connecting element and the signal line has a variable capacitance. A structure is also provided in which in an exactly opposite way, the respective capacitor between the grounding conductors and the connecting element has a variable capacitance, but the capacitor between the connecting element and the signal line has an invariable capacitance. Furthermore, a method for producing such a component is also provided.

An electrical component is proposed, in particular a high-frequency microelectronic or microelectromechanical component having a base element that is provided with a feedthrough, a first conductive structure extending on an upper side of the base element being connected by the feedthrough, continuously for high-frequency electromagnetic waves, to a second conductive structure extending on a lower side of the base element. The feedthrough has the form of a right prism or cylinder, and the first and/or the second conductive structure is embodied as a planar waveguide, in particular as a coplanar waveguide. Also proposed is a method for producing an electrical component having a feedthrough for high-frequency electromagnetic waves through a base element, an electrically conductive layer being applied on an upper side of the base element and an etching mask being applied on a lower side of the base element; a trench, having at least almost perpendicular sidewalls and penetrating through the base element, then being etched into the base element in a plasma etching step; an electrically conductive layer being applied on the lower side after the etching and after removal of the etching mask; and the trench lastly being filled or lined with an electrically conductive material.

A circuit assembly for plausibility checking of sensor signals, which can be generated by at least two separate sensor elements, includes at least one evaluation and control unit which receives the sensor signals via at least one interface unit and evaluates the received sensor signals for generating sensor data. A first evaluation and control unit is configured to receive the sensor signals of a first sensor element and to generate first sensor data from the first sensor signals. The first evaluation and control unit is configured to provide the generated first sensor data via at least one interface unit to a second evaluation and control unit, which receives and evaluates the sensor signals of a second sensor element to generate second sensor data. The second evaluation and control unit compares the generated second sensor data and the generated first sensor data to each other and inspects them for plausibility.

A yaw rate sensor (10) includes a movable mass structure (12) and a drive component (13) which is suitable for setting the movable mass structure (12) in motion (14), and an analysis component (15) which is suitable for detecting a response (40) of the movable mass structure (12) to a yaw rate (Ω). A method for functional testing of a yaw rate sensor (10) includes the following steps: driving a movable mass structure (12), feeding a test signal (42) into a quadrature control loop (44) at a feed point (48) of the quadrature control loop (44), feeding back a deflection (40) of the movable mass structure (12), detecting a measure of the feedback of the movable mass structure (12), and reading out the response signal (47) from the quadrature control loop (44). In the yaw rate sensor (10) and also in the method, the readout of the response signal (47) in relation to a processing direction (45) of the test signal (42) is provided between a feed point (48) for a test signal (42) and an actuator (38) for feeding back a deflection (40) of the movable mass structure (12).
