The floating ring is disposed between the ground ring and the spiral inductor and surrounds a ring portion of the spiral inductor. A switching element, controlled by a switch control signal, selectively electrically connects the ground ring to the floating ring. The switching element includes one or more switches. The one or more switches are controlled by one or more signals of the switch control signal to adjust the inductance level of the varainductor."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Varainductor and operation method thereof based on mutual capacitance","description":"A varainductor includes a spiral inductor, a ground ring, and a floating ring.
