Abstract

A composite dielectric thin film capacitor, utilizing non-isolated overvoltage protection diodes on a silicon substrate, is used as an on-module decoupling capacitor for power supplies. The purpose of the capacitor is to provide s local switching current source for fast switching logic circuits. One requirement of the decoupling capacitor is that it contain four separate capacitors with one common electrode.
