Abstract :
An effective capacitance of a distributed RLC load for estimating short-circuit power is presented in this paper. Both resistive and inductive shielding effects of interconnects are considered and no iterations are required to determine the effective capacitance. The proposed method has been verified with Cadence Spectre. For a single switching input, the average error of the short-circuit power obtained with the effective capacitance is less than 2% for the example circuits as compared with an RLC pi model. The proposed method can be used in look-up table or k-factor based models to estimate short-circuit power dissipation in CMOS gates with complex interconnects
