Abstract:
Some features pertain to a device package that includes a die and a package substrate. The die includes a first switch. The package substrate is coupled to the die. The package substrate includes at least one dielectric layer, a primary inductor, and a first secondary inductor coupled to the first switch of the die. The first secondary inductor and the first switch are coupled to a plurality of interconnects configured to provide an electrical path for a reference ground signal. The primary inductor is configurable to have different inductances by opening and closing the first switch coupled to the first secondary inductor. In some implementations, the primary inductor is configurable in real time while the die is operational. In some implementations, the die further includes a second switch, and the package substrate further includes a second secondary inductor coupled to the second switch of the die.

Some implementations provide an integrated device that includes a capacitor and an inductor. The inductor is electrically coupled to the capacitor. The inductor and the capacitor are configured to operate as a filter for an electrical signal in the integrated device. The inductor includes a first metal layer of a printed circuit board (PCB), a set of solder balls coupled to the PCB, and a second metal layer in a die. In some implementations, the capacitor is located in the die. In some implementations, the capacitor is a surface mounted passive device on the PCB. In some implementations, the first metal layer is a trace on the PCB. In some implementations, the inductor includes a third metal layer in the die. In some implementations, the second metal layer is an under bump metallization (UBM) layer of the die, and the third metal is a redistribution layer of the die.

Abstract:
An upper planar capacitor is spaced above a lower planar capacitor by a dielectric layer. A bridged-post inter-layer connector couples the capacitances in parallel, through first posts and second posts. The first posts and second posts extend through the dielectric layer, adjacent the upper and lower planar capacitors. A first level coupler extends under the dielectric layer and couples the first posts together and to a conductor of the lower planar capacitor, and couples another conductor of the lower planar capacitor to one of the second posts. A second level coupler extends above the dielectric layer, and couples the second posts together and to a conductor of the upper planar capacitor, and couples another conductor of the upper planar capacitor to one of the first posts.

The second set of traces is coupled to the first set of traces. The second set of traces includes a third trace that is coupled to the first trace and to the second trace. The third set of traces is coupled to the first set of traces.
