Short-circuit power analysis of an inverter driving an RLC load

The demand for powerfull computational machines using scaled technologies has brought power dissipation to the forefront. Hence, there is a need to accurately model power dissipation in such technologies where both capacitive and inductive effects are important. In this paper, we accurately model short-circuit power dissipation of an inverter driving an RLC load. A closed form expression is derived based on the analysis of the inverter in different conducting regions during an input transition. We applied the proposed model to a 0.18 um Cu technology, and compared the result with SPICE simulation. Our model has an accuracy of 90% with respect to SPICE
