Abstract

At least one high voltage rated isolation capacitor is formed on a face of a primary integrated circuit die. The isolation capacitor AC couples the primary integrated circuit in a first voltage domain to a second integrated circuit in a second voltage domain. The isolation capacitor DC isolates the primary integrated circuit from the second integrated circuit die.
