The first amplifier is a differential type of amplifier, and includes one input terminal for receiving a signal and the other input terminal for receiving a reference signal which changes with a predetermined slope. The second amplifier is a single-ended type amplifier, and determines an auto zero voltage based on the amplified voltage by an auto zero operation of the first amplifier and includes a self-bias circuit using the auto zero voltage as a bias voltage. The comparator is plural, the comparators are plurality which arranged in a row direction, and outputs a digital value based on an analog voltage inputted to the other input terminal in parallel operation."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Solid-state imaging device, AD-converter circuit and current compensation circuit","description":"It is an object of the present invention to provide a technique for reducing the variation of a bias voltage.An analog-to-digital converter comprises a comparator including a first amplifier and a sec","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11528441","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.
