Abstract
The integrated capacitor structure comprises a first branch with a first capacitor () and a second branch with a second capacitor (). The second capacitor () has a higher capacitance density and a lower breakdown voltage than the first capacitor (). The first branch has a shorter RC time constant than the second branch, such that a voltage peak will substantially follow the first branch. This first capacitor () has a sufficient capacity to store the charge of the voltage peak. In one embodiment, the second capacitor () is a stacked capacitor. The structure is suitable for ESD-protection and may, to this end, additionally comprise diodes () and resistors ().
