The circuit arrangement comprises a delta-sigma modulator with at least one control loop to perform a force feedback that resets the secondary mass into its resting state by applying a reset signal, wherein the reset signal forms a modulator output signal of the delta-sigma modulator, a correction unit that receives the modulator output signal and that is operated to generate a corrected modulator output signal that corresponds to an actually acting feedback force, a demodulator that is connected to the correction unit for demodulation of the corrected modulator output signal, and a filter arrangement to filter the demodulated signals and to output a rotary rate signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Circuit arrangement and method for the digital correction of modulation effects in electromechanical delta-sigma modulators","description":"The present invention relates to a circuit arrangement and a method for reading a capacitive vibratory gyroscope with an at least primary mass and at least one secondary mass that is connected to the ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11268828","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
