Abstract
A variable inductor which comprises a primary conductor, first and second secondary conductors and one or more switch. The primary conductor has a first node and a second node, wherein the first node is used to connect a first external component and the second node is used to connect a second external component. The first and second secondary conductors magnetically couple to the primary conductor. The one or more switch has two sides connected to the first or second secondary conductor, respectively. The first and second secondary conductors are formed a single-loop structure with two or more changeable current paths which are operated by the states of the one or more switch. An integrated circuit using the variable inductor is also introduced.
