The current generation section has at least one current source transistor group including a plurality of current source transistors and generates an output current based on a value of a digital input signal. The current source transistor bias voltage keeping section has a plurality of cascade transistor groups each including cascade transistors connected in series to the current source transistors and keeps bias voltages of the current source transistors constant. The cascade transistor group switch section selects one of the plurality of cascade transistor groups. The conversion section performs current-voltage conversion of the output current supplied via the selected cascade transistor group."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"DA converter, solid-state imaging device, driving method of solid-state imaging device, and electronic apparatus","description":"Disclosed is a digital-analog converter including a current generation section, a current source transistor bias voltage keeping section, a cascade transistor group switch section, and a conversion se","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9681080","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.
