Abstract :
A delay and power model of a CMOS inverting repeater driving a resistive-capacitive load is presented. The model is derived from Sakurai´s alpha-power law and exhibits good accuracy. The model can be used to design and analyze those CMOS inverters that drive a large RC load when considering both speed and power. Expressions are provided for estimating the propagation delay and transition time and exhibit less than 27% discrepancy from SPICE for a wide variety of RC loads. Expressions are also provided for modeling the short-circuit power dissipation of a CMOS inverter driving a resistive-capacitive interconnect line which are accurate to within 15% of SPICE for most practical loads
