The capacity measuring circuit additionally includes a delta-sigma modulator. The delta-sigma modulator is configured to receive a charge from a second terminal of the capacity to be measured and to provide a digital output signal which is dependent on a quantity of the charge received from the capacity to be measured. The capacity measuring circuit may be employed in a sensor system."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Capacity measuring circuit, sensor system and method for measuring a capacity using a sinusoidal voltage signal","description":"A capacity measuring circuit includes a measuring voltage source configured to feed a sinusoidal voltage signal to a first terminal of a capacity to be measured so as to cause a temporal change in a c","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9612266","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.
