Article comprising a variable inductor

摘要

A micromechanical variable/tunable inductor (100) is disclosed. The present inductor comprises at least two elements (104,110) capable of supporting spatial electromagnetic coupling and means for varying a geometrical relationship thereof. Varying the geometrical relationship between such elements varies the inductance of the inductor. In some embodiments, the geometrical relationship that is varied is the spacing between the two elements. The spacing is varied by creating a differential movement between such elements. In further embodiments, the present invention comprises resonant circuits incorporating such variable inductors, and oscillators including such resonant circuits. <IMAGE>
