Modeling leakage currents of different CMOS cells by the power contributors method

This paper illustrates the Power Contributors method into modeling of leakage currents and static power consumption for different CMOS cells from the NanGate OpenCell library. These cells are decomposed into Power Contributors, and all the leakage currents which run through their terminals, are modeled in a systematic way. The results prove that this method facilitates the modeling procedures, without sacrificing their accuracy.
