Abstract: An oscillating circuit includes an analog oscillation element. The oscillating circuit includes at least one analog-to-digital conversion device. A method is for operating an oscillating circuit, in which a mechanical oscillator oscillates at a natural frequency. The oscillation amplitude is measured and digitized. A digital control signal is generated from this with the aid of a digital amplitude controller. A driving signal is generated, in turn, from the digital control signal, the driving signal driving the mechanical oscillator with the aid of a drive unit. This control loop stabilizes the oscillation amplitude.

Abstract: A sensor having at least one actuation/detection device, one actuation unit, and one analyzing unit. In a first operating state, the actuation/detection device is connected to the actuation unit and, in a second operating state, the actuation/detection device is connected to the analyzing unit.

Abstract: A method for the compensation of component tolerances of a number of similar components, in particular capacitors in analog-to-digital converters which are connected to a common line, and whose electric value is in each case halved from component to component, the component with the smallest value being present twice. In this method, a first potential is at first applied to at least one of the components and a second potential is applied to the remaining components with lower values. A comparator then checks whether on the common line the mid-potential between the two potentials is present. There is then applied to a correction component (which is in addition connected to the common line) a variable correction voltage which is adjusted until the comparator determines the mid-potential on the common line. The determined correction voltage is finally stored as a correction value.
