Summary:PROBLEM TO BE SOLVED: To provide a novel improved integrated variable inductor and an inductor/varactor tuning circuit. SOLUTION: The magnetic field of the inductor 32 is reduced by the presence of one or more single-loop winding 34 disposed near the inductor. The single- loop winding has an open circuit, which is selectively closed, and the single loop winding is magnetically coupled to the inductor. The varactor 30 is connected to the inductor to form the inductor/varactor tuning circuit.
