An integrated circuit includes a first isolation capacitor and a second isolation capacitor. The first isolation capacitor is electrically connected to a first circuit node and has first and second capacitor plates separated by a first dielectric stack. The second isolation capacitor is electrically connected in series between the first isolation capacitor and a second circuit node, and includes third and fourth capacitor plates separated by a second dielectric stack different from the first dielectric stack.
