The first NMOS switch includes a first N-type terminal formed on a deep N-type well substrate formed on the substrate, for receiving a driving power through a first floating resistor, a P-type terminal for receiving a body power through a second floating resistor, and two second N-type terminals for receiving a gate power through a third floating resistor. The P-type and two second N-type terminals are formed on a P-type substrate formed on the deep N-type well substrate."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Radio frequency switch circuit","description":"An RF switch circuit includes an RF switch including a first NMOS switch formed on a chip substrate, a switch controller including a second NMOS switch and a PMOS switch formed on the substrate, for c","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8476959","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.
