摘要： The integrated capacitor structure comprises a first branch with a first capacitor (60) and a second branch with a second capacitor (70). The second capacitor (70) has a higher capacitance density and a lower breakdown voltage than the first capacitor (60). 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 (60) has a sufficient capacity to store the charge of the voltage peak. In one embodiment, the second capacitor (70) is a stacked capacitor. The structure is suitable for ESD-protection and may, to this end, additionally comprise diodes (21) and resistors (22).

摘要： The invention relates to a multiple-component unit in which at least two passive components have been realized one above the other. A multiple-component unit thus comprises at least one resistor and at least one capacitor, or at least two capacitors. This space-saving construction allows for a miniaturization of circuits. A further miniaturization can be achieved in that the multiple-component units are not manufactured as discrete components, but are integrated into ICs.
