Claim:
1. A method of forming a reconfigurable multi-stack inductor structure within a semiconductor structure having a first and a second metal layer, the method comprising: forming, within the first metal layer, a first inductor structure; forming, within the first metal layer, a first ground shielding structure that is electrically isolated from and circumferentially bounds the first inductor structure; forming, within the second metal layer, a second inductor structure; electrically coupling the first inductor structure and second inductor structure; forming, within the second metal layer, a second ground shielding structure that is electrically isolated from and circumferentially bounds the second inductor structure; electrically grounding the first and the second ground shielding structure to generate a first inductance value; electrically floating the first and the second ground shielding structure to generate a second inductance value; and forming, within a third metal layer of the semiconductor structure, a ground plane; and forming a first switch for electrically coupling the first and the second ground shielding structure to the ground plane.
