In the RF switch having at least one NMOS (N type Metal Oxide Semiconductor) switch changing a transmission path of an RF signal, an N type terminal formed on a first deep N type well substrate receives driving power through a floating resistor, a P type terminal formed on a first P type substrate receives body power through a floating resistor, and the two N type terminals formed on the first P type substrate receive gate power through a floating resistor, and in the switch controller having at least one NMOS switch and at least one PMOS (P type Metal Oxide Semiconductor) switch controlling changing of a path of the RF switch, an N type terminal formed on a second deep N type well substrate and an N type terminal formed on the first N type substrate receive driving power through floating resistors."},"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":"A radio frequency (RF) switch circuit in which an RF switch and a switch controller are formed on a single CMOS substrate and floating resistors are connected to a deep N type well substrate, an N typ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8461919","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.
