Title
(EN) Deeply integrated voltage regulator architectures
Abstract
(EN)

A system is disclosed. The system includes a substrate, and a first chip on the substrate, where a load circuit is integrated on the first chip. The system also includes a second chip on the substrate, where a power delivery circuit is configured to deliver current to the load circuit according to a regulated voltage at a node. The power delivery circuit includes a first circuit configured to generate an error signal based at least in part on the regulated voltage, and a voltage generator including power switches configured to modify the regulated voltage according to the error signal, where the first circuit of the power delivery circuit is integrated on the first chip, and where at least a portion of the power switches of the power delivery circuit are integrated on the second chip.
