  • Patent number: 11573274
    Abstract: The present disclosure relates to a detection circuit for detecting oscillations of a regulated supply signal. The detection circuit includes a filter circuit to filter the regulated supply signal in order to obtain a filtered supply signal. A peak value detector circuit is designed to detect an extremum of the filtered supply signal. A comparator circuit is designed to compare the detected extreme value with a threshold value and to indicate an understepping or exceedance of the threshold value.

  • Patent number: 11536810
    Abstract: An oscillator control system that includes an oscillator structure; a phase error detector configured to generate a phase error signal based on a delayed event time signal and delayed reference signal; an analog signal path coupled between the oscillator structure and the phase error detector, the analog signal path configured to receive an event time signal and produce the delayed event time signal; a control circuit configured to generate a reference signal; a programmable delay circuit configured to receive the reference signal and induce a programmable delay on the reference signal thereby generating the delayed reference signal; and an analog delay measurement circuit configured to inject a test signal into the analog signal path, receive a delayed test signal from the analog signal path, measure an analog delay of the delayed test signal, and generate a configuration signal configured to adjust the programmable delay according to the measured analog delay.

  • Publication number: 20210405125
    Abstract: The present disclosure relates to a detection circuit 200 for detecting oscillations of a regulated supply signal 110. The detection circuit includes a filter circuit 210 to filter the regulated supply signal in order to obtain a filtered supply signal 212. A peak value detector circuit 220 is designed to detect an extreme value of the filtered supply signal. A comparator circuit 230 is designed to compare the detected extreme value with a threshold value and to indicate an understepping or exceedance of the threshold value.

  • Patent number: 8675790
    Abstract: A receiver is provided with a digital signal processing circuit to process a receive signal. In addition, the receiver includes an interference detector to detect an interference scenario affecting reception of the signal by the receiver. Depending on the interference scenario detected by the interference detector, the digital signal processing circuit is adapted.

  • Patent number: 7495595
    Abstract: A filter arrangement comprises a switching element coupled to a filter input, wherein the switching element is controllable by a reference clock signal. The filter arrangement further comprises an input storage element, an output storage element, and a first and a second auxiliary storage element. The first and the second auxiliary storage element can each be connected in parallel to the input storage element or to the output storage element depending on a switching signal. The output storage element is coupled to a filter output. The filter arrangement can be used as a loop filter in an analog-to-digital converter, wherein the output signal of the filter arrangement is quantized to provide an output word. Respective feedback signals can be generated from the output word and be provided to the storage elements.

  • Patent number: 5187097
    Abstract: The disclosure is directed to a large composting system as well as to a new composting method for the automatic production of compost. A mobile layer rearranging unit includes a conveyor system which is changeable with respect to length can be remote-controlled so that the influx of rotting matter is optimized according to throughput and rotting time and the rot loss is compensated for by repeatedly restoring the complete rot height. The required space requirement is less than before. Any mechanical intervention has a loosening effect, particularly in that the working device comprises upwardly working digging and conveyor wheels. All important parameters for the compost ripening can be monitored via free programming as well as by control by the system maintenance personnel.
