Abstract

A high-voltage stacked capacitor includes a first capacitor and a second capacitor. Each capacitor includes a first plate comprising a first semiconductive body and a second plate comprising a floating electrode. The first and second semiconductive bodies are electrically isolated from each other. The floating electrode includes an intercapacitor node configured to self-adjust to a value less than a working voltage impressed on the stacked capacitor.
