Abstract
Embodiments herein relate to integrating FIVR switching circuitry into a substrate that has a first side and a second side opposite the first side, where the first side of the substrate to electrically couple with a die and to provide voltage to the die and the second side of the substrate is to couple with an input voltage source. In embodiments, the FIVR switching circuitry may be printed onto the substrate using OFET, CNT, or other transistor technology, or may be included in a separate die that is incorporated within the substrate.

A package comprising:
- a substrate, having a first side and a second side opposite the first side, the first side of the substrate to electrically couple with a die and to provide voltage to the die, and the second side of the substrate to couple with an input voltage source;
- and
- wherein the substrate is to include fully integrated voltage regulator (FIVR) circuitry to regulate a voltage to the die.
A method for creating a fully integrated voltage regulator (FIVR) within a substrate using an embedded die, the method comprising:
- embedding the die into a first side of the substrate, wherein the substrate includes a inductor having a first end electrically coupled to a second side of the substrate opposite the first side of the substrate, wherein a second end of the inductor opposite the first end is electrically coupled to the embedded die, wherein the embedded die includes circuitry to perform FIVR switching;
- and
- electrically coupling a connection on the substrate to the embedded die to allow the embedded die to receive a voltage external to the substrate.
A method for creating a fully integrated voltage regulator (FIVR) within a substrate, the method comprising:
- coupling a transistor onto a first side of the substrate, wherein the substrate includes a magnetic inductor having a first end electrically coupled to a second side of the substrate opposite the first side of the substrate, wherein a second end of the inductor opposite the first end is electrically coupled to the transistor and wherein the transistor is to provide FIVR switching;
- and
- electrically coupling a connection on the substrate to the transistor to allow the transistor to receive a voltage external to the substrate.
