Claim Text:
1. A reservoir capacitor, comprising: a first capacitor group having at least two capacitors, which are serially coupled to each other between a first power voltage supply terminal and a second power voltage supply terminal; a second capacitor group having at least two capacitors, which are serially coupled to each other between a third power voltage supply terminal and a fourth power voltage supply terminal; and a connection line suitable for electrically coupling a first coupling node between the at least two capacitors included in the first capacitor group to a second coupling node between the at least two capacitors included in the second capacitor group, wherein the first power voltage supply terminal and the third power voltage supply terminal are different from each other and receive different power voltages, respectively, and the second power voltage supply terminal and the fourth power voltage supply terminal are different from each other and receive different power voltages, respectively.
