Abstract:
A reconfigurable multi-stack inductor formed within a semiconductor structure may include a first inductor structure located within a first metal layer of the semiconductor structure, a first ground shielding structure located within the first metal layer that is electrically isolated from and circumferentially bounds the first inductor structure, and a second inductor structure located within a second metal layer of the semiconductor structure, whereby the second inductor structure is electrically coupled to the first inductor structure. A second ground shielding structure located within the second metal layer is electrically isolated from and circumferentially bounds the second inductor structure, whereby the first and second inductor generate a first inductance value based on the first ground shielding structure and second ground shielding structure being coupled to ground, and the first and second inductor generate a second inductance value based on the first ground shielding structure and second ground shielding structure electrically floating.
