Claim:
1. An integrated circuit, comprising: a first die lying within a first geometric plane and comprising a first circuit, electrically coupled to a first switch circuit via a first signal path, wherein the first switch circuit comprises a first voltage supply circuit for providing a first power supply voltage to the first signal path; and a second die lying within a second geometric plane that is different from the first geometric plane, the second die comprising a second circuit, electrically coupled to a second switch circuit via a second signal path, wherein the second switch circuit comprises a second voltage supply circuit for providing, independently from the first voltage supply circuit, a second power supply voltage to the second signal path, wherein the first switch circuit is electrically coupled to the second switch circuit via a third signal path, and wherein the first switch circuit is configured to control the second switch circuit and dynamically control the first and second power supply voltage via the first signal path, the second signal path, and the third signal path.
