Variable inductance element using an inductor conductor |
摘要 |
A variable inductance element comprising an inductor conductor 10 having a predetermined shape formed on an insulation layer 40 on the surface of a semiconductor substrate 42, switches 16 and 24 for shorting portions of the inductor conductor 10, and input/output terminals 12 and 14 provided at the respective ends of the inductor conductor 10. When switches 16 and/or 24 is in the on state, the function as an inductor having a smaller inductance than the overall inductor conductor 10 is obtained. The inductance of this variable inductance element can be changed by external control, while manufacturing is easy and formation in a unitized manner with an integrated circuit or other semiconductor device is enabled.
