Abstract
Disclosed is a variable inductor or inductor module with a varying inductance, wherein the variable inductor or inductor module changes inductor ring spacing and the distance between the inductor and a substrate using a MEMS driver, thereby enabling variances in the inductance.
Claims20
A variable inductor or inductor module, comprising:
- a substrate;
- an inductor coil above the substrate, and having a reference inductance value;
- and
- a micro-electromechanical system (MEMS) driver that responds to an electrostatic force, configured to be turned on or off in response to a control signal and is configured to increase a distance between at least part of the inductor coil and the substrate when the MEMS driver is turned on, and to maintain the inductor coil in a default position when turned off.

A variable inductor or inductor module, comprising:
- a substrate;
- an inductor coil comprising a plurality of split coils connected to each other above the substrate, the inductor coil having a reference inductance value;
- and
- a plurality of micro-electromechanical system (MEMS) drivers that respond to a plurality of electrostatic forces, wherein the plurality of MEMS drivers are respectively connected to the plurality of split coils, configured to be turned on or off in response to a plurality of control signals, and configured to increase a distance between the split coils and the substrate when turned on, and to maintain the split coils in a default position when turned off.

A variable inductor or inductor module, comprising:
- a substrate;
- a multi-coil inductor comprising a first coil and a second coil above the substrate, and having inductance values;
- a first micro-electromechanical system (MEMS) driver that responds to a first electrostatic force, configured to be turned on or off in response to a first control signal, and configured to increase a first distance between the first coil and the substrate when turned on, and to maintain the first coil in a first default position when turned off;
- and
