Patent ID: 8848390

Claim:
A multi-chip module comprising: a chip stack package comprising at least one pair of stacked dies, the dies having overlapping opposing faces; and at least one capacitive proximity communication (CPC) interconnect between the pair of stacked dies, the CPC interconnect comprising a first capacitor plate at a first one of the overlapping opposing faces and a second capacitor plate at a second one of the overlapping opposing faces spaced from and aligned with the first capacitor plate, the CPC interconnect further comprising an inductive element connected in series with the first capacitor plate and second capacitor plate, wherein the capacitor plates form part of a capacitor and the capacitor cooperates with the inductor element to form a LC circuit having a resonant frequency; wherein the inductor element includes a first inductor, at the first die, connected in series with the first capacitor plate and a second inductor, at the second die, connected in series with the second capacitor plate.
