A circuit arrangement includes a phase locked loop configured to produce a controlled frequency. The phase locked loop has an actuating input and a control loop output, with it being possible to tap off the frequency at the control loop output. In addition, a frequency meter is provided, which is connected to the control loop output of the phase locked loop. The frequency meter is configured to measure the frequency of the phase locked loop. Finally, a computation unit is provided in order to determine a gradient associated with the phase locked loop and generate a correction value based thereon, wherein the correction value is employed to mitigate a deterioration in the loop bandwidth due to variations in the gradient.

A frequency-dividing circuit arrangement is disclosed that includes a divider chain having a plurality of frequency divider stages. The frequency dividers can be changed over between the division ratios 2 and 3. At least that frequency divider that is arranged on the output side of the divider chain has an additional through-switching input that makes it possible to switch through the input signal to the output of the divider stage without influencing the delay-time effects of the divider stage. The advantages of a cascaded 2/3 divider chain, such as a high cut-off frequency, a simple design and the ability to arbitrarily expand, are thus achieved without accepting a lower limit of the range of possible division values.

A belt tensioner for a safety-belt restraint system in a vehicle, which can be triggered in the event of a collision or the threat of a collision, includes a device for tensioning a safety belt that is restraining an occupant, by displacing part of the safety-belt restraint system. The belt tensioner has a drive for the displacing the part, which drive comprises a repeatedly chargeable spring-energy store, as well as a spring-energy store charging device for repeatably charging of the spring-energy store once it has been discharged. The spring-energy store charging device transmits to the spring-energy store for the purpose of charging it, a tensile force that is applied to the safety belt to unwind it from a belt winding device in the course of a fastening operation by the occupant.

The phase-locked loop has a pulse generator has a phase detector which is intended to compare a reference signal with an oscillator signal, and a detector output for tapping off a phase comparison signal. The pulse generator is used to produce a pulse-width-modulated pulse signal and has a generator output, from which the pulse-width-modulated pulse signal is tapped off. A selection unit is furthermore provided and is connected, on the input side, to the detector output and to the generator output, and is designed in such a manner that either the phase comparison signal or the pulse signal can be tapped off from an output of the selection unit using a control signal applied to a control input of the selection unit.

A charge pump has a reference stage that simulates the output stage of the paths, at least in terms of the output-side transistors of the paths. An equivalent symmetrical current is generated on a reference stage. The equivalent symmetrical current replicates the fault current and controls a device for regulating the second path.

The invention relates to an optoelectronic component for converting electromagnetic radiation into an intensity-dependent photoelectric current. The component includes one substrate which is formed especially according to CMOS technology. The substrate has an integrated semiconductor structure and an optically active thin layer structure which is situated upstream in the direction of light incidence. The structure includes a layer of a transparent conductive material and at least one layer of semiconductor material, which are arranged on an isolating layer, inside which connection means are provided for establishing a connection between the optically active thin layer structure and the integrated semiconductor structure arranged on the substrate. The aim of the invention is to develop one such optoelectronic component in such a way that the electrical connection between the layer of transparent conductive material and an electrical potential connection can be established in a technically simple manner. To this end, the layer of transparent conductive material can be connected to the potential connection arranged outside the pixel arrangement by means of an additional conductive structure formed on the substrate.
