Modeling the CMOS short-circuit power dissipation

This paper presents a detailed analysis of the CMOS short-circuit power dissipation, on the basis of an elementary CMOS inverter. Accurate, analytical expressions for the inverter output response to an input ramp are derived, which result in an improved formula for the calculation of the short-circuit power dissipation. This improvement is due to the fact that the new derivations take into account the complete expression of the short-circuit current
