The PMOS transistor pair includes first and second PMOS transistors, and the NMOS transistor pair includes first and second non-doped type NMOS transistors as a depletion type of NMOS transistors in which a channel region is formed in a P-type substrate without a P well. The output circuit section includes a first current mirror of a folded cascode type connected with the first and second non-doped type NMOS transistors, and outputs an output voltage in response to a current from the first current mirror."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Differential amplifier circuit, data line driver using the same, and liquid crystal display apparatus","description":"A differential amplifier circuit includes: an NMOS transistor pair connected with a non-inversion input terminal and an inversion input terminal; a PMOS transistor pair connected with the non-inversio","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8542222","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.
