    Abstract: Techniques and mechanisms for determining an operational mode of a voltage regulator. In an embodiment, an integrated circuit (IC) die is coupled to receive power from a voltage regulator (VR) via a power delivery network (PDN) which comprises circuitry in or on a substrate, such as that of a printed circuit board. The IC die receives from the substrate information indicating a characteristic of a parasitic impedance at the substrate. Based on the information, a controller unit at the IC die selects one of multiple VR modes which each correspond to a respective one of different parasitic impedance characteristics. The controller then signals the VR to provide the selected mode. In an embodiment one of the VR modes corresponds to a relatively high impedance, and also corresponds to a relatively stable sensitivity function in a frequency range above a control bandwidth.

    Abstract: Technologies for low-leakage and low series resistance on-chip capacitors are disclosed. In the illustrative embodiment, each electrode of a capacitor is formed from two metal layers and vias between the metal layers. A high-k dielectric layer is between the metal layers. The electrodes are displaced relative to each other on the plane defined by the high-k dielectric layer. As a result, electric field lines of the capacitor are parallel to the high-k dielectric layer. The electrodes can be displaced from each other by more than the thickness of the high-k dielectric layer, reducing the leakage current through the high-k dielectric layer as compared to a capacitor with field lines perpendicular to the high-k dielectric layer. Such a capacitor may be used to provide power to circuits in a low-power state with little leakage current and/or may be used to absorb radiofrequency (RF) interference.

    Abstract: Embodiments include apparatuses, methods, and systems with cross-coupling noise reduction in circuits. In embodiments, a circuit may include a common inductor and a negatively coupled inductor pair connected or coupled between the first inductor and a first load and a second load. The negatively coupled inductor pair may include a first and a second inductor. The first inductor may be connected or coupled to the first load and the second inductor may be connected or coupled to the second load to reduce cross-coupling noise between the first load and the second load. Examples of passive structures that may be used to implement the circuit are also described. Other embodiments may also be described and claimed.
