The differential stage includes a first differential pair with one of an input pair thereof connected to the first input terminal (T1) and the other connected to the output terminal, a second differential pair with one of an input pair thereof connected to the first input terminal (T1) and the other connected to the second input terminal (T2), a first current source for supplying current to the first differential pair, a second current source for supplying current to the second differential pair, and a load circuit connected to the output pairs of the first and second differential pairs. One of the output pair of the first differential pair is connected in common to one of the output pair of the second differential pair, and their common connection node constitutes the output terminal of the differential stage."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Differential amplifier","description":"A differential amplifier has first and second input terminals (T1, T2), an output terminal, a differential stage connected to the first and second input terminals, and an amplification stage having an","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8514157","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.
