A common capacitor of the charge transfer amplifier may sample both the reset potential and the transfer potential such that a change in potential (and corresponding charge change) on the capacitor represents the difference between the transfer potential and reset potential, and the magnitude of this change is amplified by the charge change being transferred between the common capacitor and a second capacitor selectively coupled to the common capacitor."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image sensor having column-level correlated-double-sampling charge transfer amplifier","description":"Correlated double sampling column-level readout of an image sensor pixel may be provided by a charge transfer amplifier that is configured and operated to itself provide for both correlated-double-sam","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11516422","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.
