Abstract
An integrated circuit (IC) die may include a substrate layer and an inductor with an associated capacitance formed on one of multiple metal layers above the substrate layer. Power shielding strips may be formed between the inductor and the substrate layer. Portions of the power shielding strips may be selectively activated to adjust the capacitance of the inductor. As an example, switches may be coupled to the power shielding strips to selectively couple a portion of the power shielding strips to a ground voltage to increase the capacitance of the inductor. As another example, a fuse element may be used to selectively activate desired portions of the power shielding strips.
