Abstract :
This paper presents a switch-level simulation-based method for estimating quiescent current values. The simulator identifier transistors that are in the proper state to experience leakage mechanisms. This information is combined with data about both the size of these transistors and various process parameters in order to calculate the actual I/sub DDQ/ value. SPICE simulation results are also presented on a variety of circuits to both calibrate the simulator, and to demonstrate state, time and sequence dependencies of circuits.
