Beschreibung
Zusammenfassung:	In one or more embodiments, circuitry is provided for isolation and communication of signals between circuits operating in different voltage domains using capacitive coupling. The capacitive coupling is provided by one or more capacitive structures having a breakdown voltage that is defined by way of the various components and their spacing. The capacitive structures each include three capacitive plates arranged to have two plates located in an upper layer and one plate located in a lower layer. A communication signal can be transmitted via the capacitive coupling created between the lower plate and each of the upper plates, respectively.
