Abstract:
1. An inter-substrate communication system, comprising: a plurality of substrates arranged together in a stack; on at least a first one of the substrates, a plurality of electrical transmitting elements, wherein each of the transmitting elements transmits a signal in a corresponding separate channel from a set of channels during a different assigned time slot in a set of time slots, wherein each transmitting element is active in its assigned time slot and is inactive during all time slots in the set of time slots except its assigned time slot, and wherein the electrical transmitting elements include a plurality of transmitting pads; on at least a second one of the substrates, an electrical receiving element electrically coupled to the electrical transmitting elements, wherein the electrical receiving element includes a receiving pad in physical opposition to all of the transmitting pads, wherein an area of the receiving pad is larger than an area encompassing all of the transmitting pads to facilitate signal coupling, and wherein the electrical receiving element is coupled to a de-multiplexer on the second substrate.
