The ultrasonic sensor circuit generates a sensing voltage corresponding to a received ultrasonic signal to provide the sensing voltage to a first node. The input circuit provides the voltage of the first node to a second node. The reset circuit resets the voltage of the second node. The storage circuit stores a voltage difference between the second node and a second supply voltage terminal. The selection circuit provides a third supply voltage to a third node. The source follower outputs a current corresponding to a voltage between a first electrode and a control electrode via an output terminal. The compensation circuit provides a compensated sensing voltage to a control electrode of the source follower."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Ultrasonic sensing circuitry and releaded driving method, detection substrate and touch panel","description":"An ultrasonic sensing circuitry is disclosed which includes an ultrasonic sensor circuit, an input circuit, a reset circuit, a storage circuit, a selection circuit, a source follower, and a compensati","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11295105","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.
