Abstract
In one or more embodiments, a system is provided for communicating between different voltage domains using N+1 capacitive-coupled conductive lines to provide N communication channels. For instance, bi-directional communication (e.g., a first communication in a first direction and a second communication path in the opposite direction) may be provided using three capacitive-coupled signal paths. Two of the signal paths are used as single-ended (i.e., non-differential) signal paths. The third signal path is used to suppress voltage disturbances between two voltage domains.
