ABSTRACT:
A system is disclosed for coupling electrically isolated circuits in a monolithic integrated circuit. A signal coupler is integrated on a chip together with a primary circuit and a secondary circuit which is to be coupled to the primary circuit. The signal coupler comprises an integrated coupling capacitor which consists of a coplanar conductor path arrangement embedded into a passivation layer, the passivation layer being applied to an insulating substrate, preferably sapphire.
